Nonmetals Definition and Properties

Nonmetals Definition and Properties A nonmetal is simply an element that does not display the properties of a metal. It is not defined by what it is, but by what it is not. It doesnt look metallic, cant be made into a wire,  pounded into shape or bent, doesnt conduct heat or electricity well, and doesnt have a high melting or boiling point. The nonmetals are in a minority on the periodic table, mostly located on the right-hand side of the periodic table. The exception is hydrogen, which behaves as a nonmetal at room temperature and pressure and is found on the upper left corner of the periodic table. Under conditions of high pressure, hydrogen is predicted to behave as an alkali metal. Nonmetals on the Periodic Table The nonmetals are located on the upper right side of the periodic table. Nonmetals are separated from metals by a line that cuts diagonally through the region of the periodic table containing elements with partially filled p orbitals. The halogens and noble gases are nonmetals, but the nonmetal element group usually consists of the following elements: hydrogencarbonnitrogenoxygenphosphorussulfurselenium The halogen elements are: fluorinechlorinebromineiodineastatinePossibly element 117 (tennessine), although most scientists think this element will behave as a metalloid. The noble gas elements are: heliumneonargonkryptonxenonradonelement 118 (oganesson). This element is predicted to be a liquid but is still a nonmetal. Properties of Nonmetals Nonmetals have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily. Nonmetals display a wide range of chemical properties and reactivities. Summary of Common Properties High ionization energiesHigh electronegativitiesPoor thermal conductorsPoor electrical conductorsBrittle solids- not malleable or ductileLittle or no metallic lusterGain electrons easilyDull, not metallic-shiny, although they may be colorfulLower melting points and boiling point than the metals Comparing the Metals and Nonmetals The chart below displays a  comparison of the physical and chemical properties of the metals and nonmetals. These properties apply to the metals in general (alkali metals, alkaline earth, transition metals, basic metals, lanthanides, actinides) and nonmetals in general (nonmetals, halogens, noble gases).

Smith defined it as the immigration of the brightest and best citizens to another country that causes harm to the economy of their homeland, thereby providing benefits to the other countries. Fleeing to other countries to get education weakens the economy of the country since most of the talent settle abroad.

Export Management Task Article Example | Topics and Well Written Essays - 2000 words

Export Management Task - Article Example For all of you who are involved in the industry and to those of you who have had the occasion to become involved on a personal level, You will no doubt agree with me when I say that it is an industry which is predicated on logistics, scheduling, and documents. Moreover, all of the logistics must be arranged far in advance, the scheduling must all come together into one unit at a specific time, and at a specific place, and all of the documentation must be accomplished accurately, and on time, in accordance with previously stipulated agreements. Having said that, I will now present the various components and aspects which comprise the Export Management Task. Export sales contracts can be formal or informal, depending on the foreign buyer. One should be cautioned that any contract which is made quickly and informally when some of the conditions are assumed or left to be clarified later, is a dangerous, ill advised, and not a good practice standard. Of course, most of us are aware of off ers to sell which are presented over the phone, which covers the product to be sold, the quantity, the price per unit, outlining delivery, the terms, and the medium of payment, which is often accepted by the foreign buyer. Also, we are familiar with a call from the buyer, with an offer to buy. offer to buy. 2This type of contract may be preceded by a series of offers and counter offers before the final offer and acceptance. This type of contract remains informal if it is not confirmed in writing. This type of contractural practice is most common and acceptable between branches of the same company, or between long standing trade partners, or between very reputable companies who trade in commodities which are prone to rapid changes in prices. It is my caution to you, that unless one of the three above-mentioned conditions are characteristic of your transaction, then this informal mode, should not be your practice. The most assured way to a void any and all misunderstandings, is to get the buyer to agree to the use of what is commonly referred to as General Standard Conditions. "These are standardized contract terms that permit the parties to refer to a pre- established set of rules that can be incorporated into the contract"(SIT). If you elect to choose this standardized proforma, then you must by all means, become keenly familiar with the contents, because once the generalized Standard Conditions have been adopted, they are legally binding whether or not both parties are aware of and understand every provision"(SIT) According to the Secrets in International Trade, an offer to sell may also be made via telex, courier, air mail, cable, facsimile and today even via e-mail. The exporter confirms the terms and stipulations of the sale via a proforma invoice: the proforma invoice will detail the entire order, The type of shipment ( i.e., f.o.b. Plymouth) quantity, type of item, unit cost, and total cost. As an addendum one might also include certain terms such as the name and address of the preferred bank, and the preferred shipping3 date. Upon receipt of the proforma invoice, the buyer will confirm his acceptance by

A concluding theme Essay Example | Topics and Well Written Essays - 1000 words

A concluding theme - Essay Example The upper class mainly comprise of the top world economic giants followed by the developing world that comprise most countries in the Far East such as Malaysia and finally the lower class where most states in Africa and Asia belongs. It is on this backdrop that the books Poor Economics: A Radical Rethink of the Way to fight Global Poverty by Abhijit V. Banerjee and Esther Duflo , Whiteman by Tony d’Souza, and Little Princes by Conor Grennan where authored to evaluate these changing cultural dynamics across the globe. Aside from death and taxes, there exists one more aspect that can be added to life certainties list in school thought policy. These are mechanisms on how to extricate the global south from poverty. According to the World Bank’s definition of poverty, poverty is the inability for a person to utilize at least $ 1.25 in a day; 1. 3 billion people across the globe live below these standards. Paul Collier, a development economist refers these as the bottom billions. There is increased desire for the world to help people in the third world countries. It is on this premise that an academic discipline has emerged with several scholars advances theories related to poverty alleviation. These scholars include Jeffrey Sachs with the Pre- Foreign –Aid, Dambisa Moyo and the theory of Trade, not Aid and Paul Romer’s view of creating charter cities. It tempts to make an assumption that all books on issues related to global development seems to advance poverty alleviation theori es to assist in poverty reduction in the Global south (Abhijit and Duflo 297). Abhijit and Duflo have alienated their development concept on possible ways of reducing poverty in the global south through development of a modest premise outside the anti- foreign aid and pre- foreign aid discussions. They argue that poverty alleviation strategies on international development aimed at alleviating poverty in the developing nations have to be formulated on an international platform.

Kristina Laycock ICT and My Everyday Life :: ICT Essays

This report is going to be based on the different technologies I use at home, at school, with friends and at work. I am going to evaluate the extent of my needs for these technologies. Below is a list of the technologies I use at home, school and work: Home School Work Internet Internet Touch Screen Email Mobile Telephone Mobile Telephone SMS (Simple Message Service) Smart Boards SMS (Simple Message Service) WAP (Wireless Application Protocol) Lap top Mobile Telephone Email DVD’s SMS (Simple Message Service) Teletext PDA’s (Personal Digital Assistants) The Internet: I use the Internet to communicate with friends and family at home by visiting chat rooms on-line, it is very efficient and is cheaper than a phone call. I don’t just use the Internet for social reasons; I use it for schoolwork and coursework. The Internet helps adults as well as children; you can do research on just about anything by using search engines. I also use the Internet for revision there are many different sites you can visit that helps you with last minute revision. Email: emailing is another good way of communicating with people and having a laugh. I use my email account to contact teachers as well as friends to get some revision work sent to me, when I am not at school or during the holidays. I also use it to get coursework marked, it saves the waste of paper – I just print off the finishing copy! Mobile telephones: mobile telephones are a way of contacting family and friends when you are out and about; they are also great if you need to contact someone in an emergency, i.e. emergency services. However, there are a few disadvantages with mobile telephones; in certain areas (on top of hills, under bridges etc) you can loose reception on your mobile telephone, which means you are unable to make or receive calls. Also you have to make sure the battery is charged, because if it is not your mobile will go dead and therefore you will be unable to use it. I use my mobile constantly to make arrangements with friends and to keep in touch with family; I don’t know what I would do without it. My mobile also comes in use when I am at work on a weekend; I use it to contact my mum to tell her what time I need picking up. I also use it to keep in contact with my boss so she can tell me if she wants me to work extra hours or if I don’t need to work. SMS (Simple Messaging Service): SMS is a cost efficient service set up so the public can communicate with each other through text.

Pride and Prejudice Analysis Essay

Elizabeth Bennet receives two proposals; one from Mr Collins and one from Mr Darcy. Mr Collins was a tall and heavy looking man of twenty-five years. Although he was polite and well mannered he was also pompous and had a self-inflated ego. He always made ‘never ending speeches about nothing’ and bored everyone to death. Mr Collins flattered everyone constantly but sometimes inappropriately. ‘He begged to know which of his fair cousins the excellence of it’s cooking was owed.’ -By this, Mrs Bennet was offended and assured him they were in fact able to keep a good cook. This showed his lack of judgement in when to compliment. He was also quite absurd and Mr Bennet’s sarcasm often went completely unnoticed. For example, on page 54, Mr Bennet asked if his flatteries were prepared and Mr Collins admitted that sometimes he would think of them for his amusement! Lady Catherine de Bourgh who was his patroness employed him. He grovelled to her constantly as she paid his way; because of her, he was middle/upper class. He was a clergyman at Hunsford near Rosings, Lady Catherine de Bourgh’s home. When Mr Bennet dies, Mr Collins will inherit Longburn, as Mr Bennet cannot leave the house to his wife; women couldn’t inherit. In Mr Collins’ letter, he proposes to make peace with the family. Mr Darcy on the other hand was very good looking. ‘He soon drew the attention of the room by his fine tall person, handsome features, noble mien†¦Ã¢â‚¬â„¢ He is also described as ‘a fine figure of a man’. But he was soon to be discovered to be ‘proud above his company’. He was clever, but at the same time he was ‘haughty, reserved and fastidious’. He owned Pemberly Estate and got one thousand a year. -He was upper class and he knew it; ‘He had seen a collection of people in whom there was little beauty and no fashion for none of whom he had felt the smallest interest.’ Darcy and Bingley had a good friendship despite many differences. ‘Bingley was sure of being liked wherever he appeared; Darcy was continually giving offence.’ Darcy had no sense of humour and admitted it. He couldn’t see the funny side of life whereas Bingley was light hearted and liked to enjoy everything he did. In the past Wickam and Darcy had a disagreement. Mr Darcy’s father had promised Wickam a place in the church but when he died Darcy refused to help him. Mr Collins first hints on his future plans in his letter to the Bennets when he writes; ‘I cannot be otherwise than concerned at the means of injuring your amiable daughters, and beg leave to apologise for it, as well as to assure you of my readiness to make them every possible amends.’ On the first day of staying at Longburn, he, in a conversation to Mrs Bennet said; ‘I can assure the young ladies that I come prepared to admire them.’ -Here he gave Mrs Bennet a small glimpse of his intentions. Jane Austin then gave it away saying that now having a good house and income; Mr Collins was in want of a wife. He was also pleasing Catherine de Bourgh who thought he should marry. So for the first evening Jane was the settled choice being not only the eldest, but the prettiest -this was, until he was informed by Mrs Bennet that she was soon to be engaged to Bingley (exaggeration). Then at the Netherfield Ball he asked Lizzy to dance several times and she realised she was the chosen one out of the five sisters. Mr Darcy on the other hand was far from admiring Lizzy at first and when Mr Bingley suggested he dance with her at the Meryton Ball he replied that he had not the least intention of dancing. -Bingley was dancing with the only good looking girl in the room. Here he was referring to Jane. He said Lizzy was ‘tolerable, but not handsome enough to tempt me.’ Then at Sir William Lucas’s party, William tried to pair up the two of them and Darcy did not resist, but Lizzy brushed him off with; ‘I have not the least intention of dancing.’ -this was pay back. It was at this party that Darcy realised his true feelings for her. At Netherfield when Jane went to stay, she fell ill and Lizzy being worried came to visit. Here, she noticed that Darcy was constantly watching her. Miss Bingley who secretly liked Darcy, in seeing that he was drawn to Lizzy tried to turn him against her. But all in vain, for whatever she said, he just stuck up for Elizabeth. Miss Bingley, in Mr Darcy’s defending her said; ‘I am afraid Mr Darcy that this adventure has rather affected your admiration for her fine eyes.’ I think when she says this she’s half-teasing and half jealous of him liking her. Before proposing, Mr Collins said to Mrs Bennet, ‘May I hope madam, for your interest with your fair daughter Elizabeth, when I solicit for the honour of a private audience with her in the course of this morning?’ -Here, he was basically asking Mrs Bennet’s permission to propose. He then launched straight into his ‘speech’. Mr Darcy came to visit Lizzy and at first made light conversation, asking about her health. Then there was an awkward silence where he must have been trying to think of how to start before proceeding. -Differences are already showing through. Mr Collins first said he’d chosen Lizzy almost as soon as he’d met her (which was a lie) and went on to specify his reasons for marrying her. He, as a clergyman wanted to set an example to the rest of the parish, he thought it would make his happy and he was following Lady Catherine de Bourgh’s advice. He’d obviously planed out his speech carefully but in his reasons, he had not mentioned that he was in love with her! Darcy on the other hand offered his hand in marriage because he did love her and his opening sentence expressed this clearly; ‘In vain I have struggled. It will not do. My feelings will not be repressed. You must allow me to tell you how I admire and love you.’ Mr Collins also made several insults to Lizzy when proposing to her without even realising it! For instance, he said that if she refuses, she my never get another offer. He also reminds her that if she stays single, all she may ever be entitled to is twenty-five pounds when her mother dies. Darcy put his foot in it too. After saying how much he loved her, he went on to say that it was not his wish to do so with her connections and status; ‘His sense of inferiority -of the family obstacles which judgement had always opposed to inclination.’ When he was turned down he thought she was just offended; ‘Could you expect me to rejoice in the inferiority of your connections? -To congratulate myself on the hope of relations, your connections?’ He also admitted to trying to split up Jane and Darcy and even ‘rejoiced’ in his success of doing so. In response to rejection, Mr Collins thinks Lizzy is playing hard to get and says this is to be expected of a lady. He goes on to say all the good materialistic reasons to marry him forgetting to mention things like love. He acts as if marrying would be a good investment for Lizzy or something. He then assured her that both of her parents approved of the marriage. Mr Darcy in response to rejection is shocked and angry but manages to control himself. He asked why he had been refused and thought she must be offended by what he had said earlier; ‘Could you expect me to rejoice in the inferiority of your connections?’ But after saying these words he accepted her answer. Both proposals were made for very different reasons; Mr Collins obviously proposed for convenience, whereas Mr Darcy was in love. Both men also reacted in different ways when turned down; although Mr Collins couldn’t take the rejection, he was not actually bothered about anything other than having his male pride hurt. -Darcy must have been extremely upset, to him Lizzy was the woman he wanted to spend the rest of his life with but he tried not to show his emotions. They both involved a lot of snobbery in their proposal speeches. They thought that Lizzy would not reject someone of the higher class and she should be grateful that she was chosen out of all the other girls; both reminded her constantly about her status. Mr Collins was more personal mentioning both what would happen when her mother and father died but Lizzy got more angry at Darcy because of things he has said and done in the past. Mr Collins and Mr Darcy both said in much detail all the pros and cons of the marriage. In conclusion, both proposals have some similarities but they differ in the essential requirement of love.

Prolonging Life Of The Terminally Ill - 1261 Words

Prolonging life of the terminally ill is a bioethical decision. Bioethics is the study of controversial ethical issues that have come about due to advances in biology, medicine, and technology. Some think it is a simple decision on whether to let the pacemaker run or turn off, while others agree that it is a much harder decision than that. The decision of prolonging life comes with medical, moral, financial and legal obstacles (Butler 2013). Making health decisions is a big part of one’s life. These decisions can affect the happiness and well being of a person. Along with these many difficult decisions come challenges and obstacles. The first major challenge when deciding whether to prolong life is the question of will this help or cure the illness? Sometimes continuing life this way will only make suffering longer. In some cases, it is not as good as it sounds because of the side effects that come along with this decision. One side effect is that prolonging life can disrupt a person s quality of life. Christiaan Barnard says that, â€Å" I have learned from my life in medicine that death is not always an enemy. Often it is a medical treatment. Often it achieves what medicine cannot achieve-it stops suffering† (Jones p.1). Although, there are cons to prolonging life there are also pros.
