In the end, this will be a huge step towards building confidence and getting the job.The ideal applicant for a job is usually young, bright, energetic and socially adept. But these are not the only qualities needed to get a job. A good self-introduction for a job interview will also include decent writing skills. Writing an essay of self-introduction for a job interview requires far more than just grammar and spelling. For a beginner, it can be a bit tricky.Here's a sample essay of self-introduction for a job interview that will help you out. Feel free to use the essay in any way you like. I just ask that you please don't re-use any part of the template. Simply modify t he content to your own use.To begin, you need to look at what experience you have. If you're from a very different world than our world, it is best to tell everyone about that part of your life. Maybe you've lived on Mars or Jupiter before. Maybe you spent some time working for NASA, but never finished high school. Whatever experiences you have, remember to include them.Next, talk about some of your personal items. Maybe you love drawing or writing poetry, or perhaps you write songs and play an instrument. You will have a lot of fun in front of the judges, if you can show off these parts of yourself.Showcase your accomplishments: Of course, to land a job, you will need to have a resume. You need to get the attention of the hiring manager. You need to get your resume noticed by that person. Therefore, the highlight of your resume needs to be something that will catch their attention.Try to emulate what you have done in the past, without copying or following your previous resume. Try something new, or simply explore a skill that you have. Sometimes, by exploring a new skill, you will be able to do things that are difficult to do, which will make your resume stand out. The key is to just get creative with it.Lastly, think of the future. You want to make sure you tell the hiring manager about your dream job, because when they find out you will already have your dream job, you will get that job!

Platinum Essays (896 words) - Chemical Elements, Transition Metals

Platinum I am a silvery metal that is as resistant to corrosion and tarnishing as gold. I am almost as rare and consequently am the likewise highly valued and used in Jewelry. I am also used in chemicals industry as a catalyst, in medicine as an anti-cancer drug, and in catalytic converters for car exhausts. I have an atomic number ok 78, my atomic weight is 195.09 (when rounded 195) and a symbol of Pt. Who am I? I'm platinum of coarse! Platinum is a member of the six transition elements in Group VIII of the periodic table known collectively as the platinum metals (ruthenium, rhodium, palladium, osmium, iridium, and platinum). The name is derived from the Spanish platina, meaning, silver. The element was discovered in South America independently by Antonio de Ulloa in 1735 and by N. Wood in 1741, but it had been in use by pre-Columbian Indians. The platinum metals are extremely rare elements; platinum itself is the most common, with an abundance in the Earth's crust of about a millionth of 1 percent, whereas the others of the group have abundance's of about one ten-millionth of 1 percent. Platinum occurs in nature as the pure metal and also in alloys with other metals of the group, principally in the alluvial deposits of the Ural Mountains, of Columbia, and of some parts of the western United States. In addition the element occurs in the mineral sperrylite and in the nickel-bearing deposits of Ontario in Canada. The large-scale production of nickel makes it feasible to recover the small amounts of platinum (only 1 part of platinum to 2 million parts of ore). The recovery of the individual platinum metals from the natural alloys is a complex process that depends upon the distinct properties of the individual elements, even though all members of the group are generally similar in their chemical behavior and are quite unreacti ve. For example, when the natural alloy of platinum, palladium, osmium, and rhodium is digested with aqua regia, the palladium and platinum dissolve and are extracted as a solution of chloropalladic acid and chloroplatinic acid. Platinum is then precipitated from this solution as ammonium chloroplatinate. Platinum is an attractive silvery white metal with a melting point of 1,774 deg C, a boiling point of 3,827 deg C and a density of 21.45 g/cu cm at room temperature. It has a coefficient of thermal expansion close to that of soda-lime-silica glass and is consequently used to make sealed electrodes in soft-glass systems. The predominant oxidation states of platinum are +2 and +4. Platinum is chemically inert and will not oxidize in air at any temperature. It is resistant to acids and is not attacked by any single mineral acid but dissolves readily in aqua regia. The metal is rapidly attacked by fused alkali oxides and by peroxides and will react with fluorine and, at red heat, with chlorine. On heating, platinum combines directly with elemental phosphorus, silicon, lead, arsenic, antimony, sulfur, and selenium, a fact that influences the use of platinum laboratory equipment. In keeping with the other members of the platinum group, the metal shows a fairly strong tendency to form complex ions. The most common Pt (II) complexes have square planar structures and are diamagnetic. Because of its inertness and attractive appearance, one of the major uses of platinum is in the manufacture of jewelry. Gold-platinum alloys, referred to as white gold, are widely used in dentistry and in the making of jewelry. Platinum and its alloys are used in the manufacture of crucibles and evaporating dishes for chemical analyses. Other applications include the formation of thermocouple wires, electrical contacts, corrosion-resistant apparatus, and the manufacture of platinum resistance thermometers used in the temperature control of furnaces. The alloy, consisting of 76.7% platinum and 23.3% cobalt by weight, forms an extremely powerful magnet. More recent applications of the metal involve the coating of missile cones and jet-engine fuel nozzles. Along with palladium, the metal absorbs large volumes of hydrogen, retaining it at ordinary temperatures but desorbing it at red heat. The fact that the absorbed hydrogen is extremely reactive suggests that it is present either as atomic hydrogen or as a very reactive platinum-hydrogen compound or complex. In finely divided form platinum
