Description
Xenon, a noble gas element of atomic number 54, was discovered and named by William Ramsay in 1898. Under standard conditions, xenon is a heavy, colorless, odorless gas that is chemically unreactive. It is the least abundant noble gas composing 0.00087% of the atmosphere, although it occurs more frequently in gases evolved from thermal springs. The principal application for the gas is in electronic devices and lamps.
Uses: filing luminescent tubes, flash lamps for photography, lasers, anesthesia, and hermetically sealed storage cases.
