Report Abuse. An inert element is an element that has no capacity to bond to other atoms. Most of the Noble elements Helium,Neon,Argon,Krypton,Xenon & Radon are unreactive. But, Xenon is. Atoms are clumps of sub atomic particles like protons,electrons & neutrons. There's more to it than that.
The six noble gases are found in group 18 of the periodic table. They are Helium, Neon, Argon, Krypton, Xenon, and Radon in order of increasing atomic weight. These elements were considered to be inert gases, as they have a closed-shell configuration, until the 1960's, because their oxidation number of 0 prevents the noble gases from forming compounds readily. This was found to be incorrect in 1962 when Neil Bartlett succeeded in making the first complex xenon compound.
