Answer 1

To stable themselves

Answer 2

Answer:

• The valency of helium is 0.
• It does not exchange or share electrons to form bonds with any other molecules. Helium has one shell (k) which requires two electrons and helium having two-electron so the outermost shell is completely filled and helium has zero valency. Therefore its valency is taken as zero.
