hy frnd your answer
Inert gases are those who has already filled its octet (last electron orbit capacity). These are He, Ne, Ar, Kr, Xe, Rn. Suppose, we are discussing the electron configuration of Ar. It is as such — 2 in K, 8 in L and 8 (Maximum) in M orbit. So they can hardly have a charged or ionic state. They are in such a saturated state that they do not want to accept or to donate electron. However I suggest that the word inert gasshould be replaced with noble gas.
I hope help you

Noble gases like He, Ne, Kr, Xe and Rn are placed in a separate groupbecause of the following reasons: They are extremely unreactive. They donot combine with any other element of the periodic table.
