Question

Which ionisation potential $$(IP)$$  in the following equations involves the greatest amount of energy ?

A. $$Na \to N{a^ + } + {e^ - }$$
B. $${K^ + } \to {K^{2 + }} + {e^ - }$$  
C. $${C^{2 + }} \to {C^{3 + }} + {e^ - }$$
D. $$C{a^ + } \to C{a^{2 + }} + {e^ - }$$
Answer :   $${K^ + } \to {K^{2 + }} + {e^ - }$$
Solution :
$${K^ + } \to {K^2} + {e^ - }.$$    Since $${e^ - }$$  is to be removed from stable configuration.
