Question

What are noble gases

Answer 1

Noble gases are the gases which are present at the last group.Usually,each and every element want to become stable.For this, they need 2 or 8 electrons in their valence shell.For fulfilling this elements either donate or accept electrons.This exchange of electrons make compounds. What is so spectacular about noble gases is that they already have 2 or 8 electrons with them.So,all they do is just relax.And thats why u cannot find noble gases in comined form.

plz..............mark my ansr as brainliest!

Answer 2

➡️ Elements , atoms of which have fully filled valence shell (outermost) hence they neither gain / lose / share electrons and are HIGHLY STABLE / LEAST REACTIVE are called noble gases .
THE NOBLE GASES ARE -
⏺He (2)
⏺Ne (10)
⏺Ar (18)
⏺Kr (36)
⏺Xe (54)
⏺Rn (86)
