Xenon was discovered in 1898 by Scottish chemist and physicist Sir William Ramsay and English chemist Morris William Travers. Ramsay and Travers used liquid air to make their discovery. When trying to identify this element there are several steps you need to take. After the air is cooled it converts into a liquid gas, the next step is to warm the liquid this boils the nitrogen off. Then argon is the next to leave the experiment. Finally oxygen boils away. These three chemicals make up 99.95 percent of air. After this procedure is over few other atmospheric gases remain. One of those gases is xenon. Ramsay and Travers first recognized the presence of xenon in liquid air on July 12, 1898. They named the element Xenon for the Greek word that means "stranger."
Xenon is a chemical element in the periodic table that has the symbol Xe and atomic number 54. This element is a colorless, heavy, odorless noble gas. Noble gas suggests a group of elements that is "too far above other elements to react with them. The noble gases are also called the inert gases. That term has the same meaning. The noble gases only react with other elements under very unusual circumstances. Also, it is in one part in twenty millionths of the Earth’s atmosphere. The element is extracted from the residues of liquefied air. This noble gas is naturally found in mineral springs.
