Xenon Bohr ModelXenon is a Block P, Group 18, Period 5 element. The number of electrons in each of Xenon's shells is 2, 8, 18, 18, 8 and its electronic configuration is [Kr] 4d10 5s2 5p6. In its elemental form xenon's CAS number is 7440-63-3. The xenon atom has a covalent radius of 140±9.pm and it's Van der Waals radius is 216.pm. Xenon is present in the atmosphere and is commercially produced as a byproduct of the separation of air into oxygen and nitrogen. Xenon was discovered and first isolated by Sir William Ramsay and Morris W. Travers  in 1898. Xenon is named from the Greek word xenon meaning foreign or strange.

Xenon compounds are considered to be toxic although xenon itself is not. Xenon information, including technical data, safety data and its high purity properties, research, applications and other useful facts are specified below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included.
