Choose the correct options :

Options

A. First Ionisation Energy of `N gt` First Ionisation Energy of O- atom
B. First Ionisation Energy of `N^(oplus) lt` First Ionsiation Energy of `O^(oplus)` atom
C. First Ionisation Energy of `N lt` First Ionisation Energy of `N^(oplus)` atom
D. First Ionisation Energy of `O^(oplus) lt` Second Ionisation Energy of O- atom

Answer

A, B, C

Explanation

The first ionisation energy of `O^(+)` is greater than the second ionisation energy of O-atom.
