Verified by Toppr

In a period the last element will have completely filled configuration by filling up that orbital completely.Hence they are called noble gases or inert elements as they do not participate in the bonding formation.They are also called zero group elements as they have zero electron affinity that is zero tendency in accepting electrons as they already have stability.

Q4
Assertion :Electron affinity of 4th period elements is less than that of 3rd period elements. Reason: Fourth period elements are larger than that of third period. Hence, accepting tendency of electrons will be less for fourth period because of large size that is because of addition of new shell.
