Noble Gases Essay, Research Paper
Noble GasesThe Noble Gases are the far right elements on the periodic table. On the earth they are scarce so we don+t see much of them. They are do not react well with anything. In fact until around the 50+s they hadn+t found anything that they would react with any of the gases. But then someone found out that Fluorine one the of most reactive elements could form compounds with Xenon. Later they found that it could react with most of the other nobles. Helium is one of the more scarce nobles on earth but in the universe it makes up 25% of it. Helium+s presence was discovered by using spectral analysis to detect helium in the sun+s spectrum. Helium is not found a lot on the earth because gravity cannot keep helium from escaping to space. Helium is found mostly in stars, where it goes through nuclear fusion with hydrogen. Most Helium comes from natural gas taps in North America. It is used in balloons and divers use it with oxygen to breath easier and to not get sick or dizzy. Neon is an element that is lighter than air. The element is found most common in the atmosphere of the earth. It is also found in the earth+s crust. It was discovered in 1898 by Sir Walter Ramsey and Morris W. Travers. Its uses include electric signs,lamps,and lasers.
Argon is the most abundant and most used noble on earth. It was discovered by Lord Rayleigh and by Sir Walter Ramsey in 1894. Argon makes up about 1.2 % of the earths atmosphere. It is found naturally in rock and in the air. It is used for electric light bulbs and floursent tubes. It is also used a lot in industry. Krypton a very rare noble was discovered by Sir Walter Ramsey and by Morris W. Travers. Traces of it are found in natural gas,hot springs and volcanoes but most of it is in the atmosphere. It is used for incadesent lights and it is used in high speed photography. Xenon is the first noble to form compounds with another element. It is very heavy and extremely rare. It was discovered by Sir Walter Ramsey and Morris W. Travers. It is found in mineral springs and in the Martian atmosphere. It is used in stroboscopes and many things to do with photography. Radon is a very heavy radioactive gas. It was discovered by Freredich E. Dorn in 1900. It is in spring water, soil, and in some rocks. It is used to cause chemical reactions in medical procedures. Even though it helps it is seen as a major health risk because it can seep through poorly ventilated houses and contribute to cancer of the lungs.
