. Which is correct about ionization potential
Which is correct about ionization potential:
(A) (IP)1 of N > (IP)1 of O
(B) (IP)2 of N > (IP)2 of O
(C) (IP)2 of Li > (IP)2 of Ne
(D) (IP)1 of Al > (IP)1 of Ca
Best Answer
Correct Option is -
(A, C)
(IP1) of N > (IP1) of O
Configuration of N (7) = 1s22s2 2p3
Configuration of O (8) = 1s22s22p4
N is half filled that’s why it requires
comparative high energy to remove
electron from it orbit than O.
(IP)2 Li > (IP)2 of Ne
(IP)2 means second ionisation
potential
Configuration of Li+ = 1s2
Configuration of Ne+ = 1s22s22p5
Li+ is fully filled.
