The Infamous Nobel Gases Report

Group 18 - The Noble Gases By Quarkem Quar Quarro and Phantism X
Noble gas refers to any element of the group of six elements in-group 18 of the periodic table. They are argon, helium, krypton, neon, radon, and xenon. Unlike most elements, the noble gases are monatomic. The atoms have stable configurations of electrons. Therefore under normal conditions
they do not form compounds with other elements.

They were generally called inert gases until about 1962 when xenon tetrafluoride, XeF4, was produced in the laboratory. This was the first report of a stable compound of a noble gas with another single element.

All of these elements have closed electronic structures (i.e., their valence shells are full) which explains their low reactivity. Because of this, the
gases that they form are all monatomic.
