16)
the answer is a(i)
1s2 2s2 2p63s1
The outer orbit contains S1 configaration. after the removal of one electron, it gets Ne configaration. so the ion is stable,So the second IP is more .

The answer is a(i).
The outer orbit contains S1 configaration. after the removal of one electron, it gets Ne configaration.
18.
