Question

what are inert gases . why do they exist as mono atom in molecules? ​

Answer 1

THE INERT GAS ARE THE GAS WHICH DOES'T UNDERGOES IN THE CHRMICAL REACTION.

THEY EXISTS IN MONO ATOMIC IN MOLECULES ITS MAIN REASON IS THAT THEY DOES NOT PERFORM CHEMICAL REACTION (VALENCY) BECAUSE THE PRESENCE OF THE CONSTANT NUMBER OF ELECTRON CONFIGARATION. JTS SHELL GET ALWAYS FUL

FOR EX SUPPOSE AN ATOMS OF AN ELEMENTS HAS ELECTRON CONFIGARATION =2, 8, 8

Answer 2

$Assalamualaikum$

Here is your answer....,

An inert gas is a gas which does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances, and were historically referred to as the inert gases. Inert gases are used generally to avoid unwanted chemical reactions degrading a sample.

Elements other than inert gases try to get stable electronic configuration by losing or gaining electrons during this process they combine with other elements or sometimes with atoms of same element. So, elements which acquired stability exist as a molecule does not exist as mono atomic elements.

I hope it will help you and mark me as a brain list answer plz.
