12 wrz 2022 · Xenon is an element with the symbol Xe, has an atomic number 54, and belongs to group 18 of the periodic table. Xe is a monoatomic, inert gas, first discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961) in the residue left after partial evaporation of liquid air (with krypton as an impurity).[1]
Chemical, physical and material properties and data of the chemical element Xenon. Shorthand electron configuration of Xenon: [Kr] 4d10 5s2 5p6 . The following table lists the ionization energies IE (ionization potentials); the IE is the energy required in electron volt (eV) per atom to separate a given electron from an Xenon atom.
Xenon is a chemical element with the symbol Xe and atomic number 54. It is a dense, colorless, odorless noble gas found in Earth's atmosphere in trace amounts. Although generally unreactive, it can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized.
