Question

2
Which of the following have maximum value of ionisation energy than oxygen? [E]

(A)F
(B) B
(C*)N
(D)C​

Answer 1

The sulfur ion has an extra shell than an oxygen ion, so the atomic size of sulfur should be greater than oxygen. Therefore, the ionization energy of an oxygen ion should be more than a sulfur ion because the electrons in oxygen are closer to the nucleus when compared to sulfur.

Answer 2

Answer:

Ionisation energy of nitrogen is found to be greater than oxygen
