Xenon

Xenon (Xe) exists as a colourless, odourless gas and is chemically inert. It has the atomic number 54 in the periodic table and belongs in Group 18, the Noble Gases. It is a non metal with the symbol Xe.

Xenon was discovered in 1898 by William Ramsay and Morris Travers. After separating liquid air into a sample they conducted spectroscopic analysis of the remaining sample. They discovered blue lines which they attributed to the new element Xenon. Xenon draws its name from the Greek word ‘Xenos’ meaning stranger. Ramsay received the Nobel Prize in 1904 for his work on the discovery of the noble gases. Xenon whilst a noble gas is relatively unreactive but compounds with oxygen and fluorine have been made. Xenon is widely used in photographic lighting and arc lamps. It is also used as an anaesthetic in medical procedures. It is located in Group 18 as a non metal gas which is odourless and colourless. It has a melting point of -118°c and a boiling point of -108°c.

FAQ's

What is the Melting Point for Xenon?

Xenon has a Melting Point of -111.9°F, meaning at -111.9°F it will turn to a liquid.

What is the Boiling Point for Xenon?

Xenon has a Boiling Point of -108°F, meaning at -108°F it will turn to a Gas.

What is the Electronegativity of Xenon?

Xenon's Electronegativty is 2.6. Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.

What is the Heat of Vaporization of Xenon?

Xenon has a Heat of Vaporization of 12.636 kJ/mol.

Uses

Used for filling flash lamps and other powerful lamps. Electrical excitation of xenon produces a burst of brilliant whtie light. Also used in bubble chambers and modern nuclear power reactors.
