Answer 2

FINAL ANSWER:-

2..Both assertion and reason are true but the reason is not the correct explanation of assertion.

REASON WHY:-

The members of the group have eight electrons in their outermost orbit (except helium which has two electrons). Thus, they have a stable configuration. Group 18 elements are gases and chemically unreactive, which means they don’t form many compounds. Thus, the elements are known as inert gases.
