1(ii)
In the 2nd period Neon has maximum Ionization Potential because:
- (a)It has unstable electronic configuration.
- (b)It easily accepts electrons.
- (c)It easily loses electrons.
- (d)The outer most shell is completely filled.

The outer most shell is completely filled.
Reason — The outer most shell is completely filled making it extremely stable and requiring more energy to remove an electron. Therefore, Neon has maximum Ionization Potential in the 2nd period.
