Xenon A very heavy, inert gaseous element of the noble gas group, occurring in the atmosphere in the proportion of one volume is about 20 millions. It was discovered by Ramsay and Travers in 1898. It can be condensed to a liquid boiling at -107° C., and to a solid which melts at ...

and the electronic configuration of its atom. The elements in rows make up 'periods' that reflect the outermost electronic shell being used. The elements in columns make up 'groups' that exhibit the same kinds of electronic and chemical behavior. Group behavior varies in a manner such that two...
The rightmost column of the Periodic Table of Elements lists the noble gases: helium, neon, argon, krypton, xenon and radon. All of these elements are gaseous at room temperature, colorless, odorless and unreactive with other elements. The noble gases share an electron configuration in which th...
As already mentioned, the Jahn–Teller effect has its roots in group theory. The essence of the argument is that the energy of the compound is stabilised upon distortion to a lower-symmetry point group. This distortion may be considered to be a normal mode of vibration, with the cor...
