Answer 2

hello dear!!

ur answer is not completely correct

ur complete answer will go like this-->

According to the molecular orbital theory Helium has two electrons in the outermost shell and thus it is chemically stable because it's duplet is complete.Hence it does not participate in the bond formation and molecule must have a bond to exist which is not in case of Helium.
