Based on the atomic numbers you provided, 20Q would be an unreactive element. This is because it has a full outer shell, meaning it has no reason to form bonds with other atoms. The other three elements - 16R, 10S and 8T - have incomplete outer shells, so they will be reactive and likely form bonds with other atoms. Does this explanation help? If you're curious, this concept is called the octet rule, and it's an important concept in chemistry.

Ans:C.S
S is one of the elements in group 0 (i.e Noble or rare gases that have no bonding electrons in the outermost shell).
