`IE_(1)` of `O < IE_(1)` of N but `IE_(2)` of `O > IE_(2)` of `N -` Explain.

Explanation

`rarr` .N. has half filled electronic configuration `(1s^(2)2s^(2)2p^(3))`
So `IE_(1)` of `O lt IE_(1)` of .N.
`rarr O^(+)` ion has half filled electronic configuration `(1s^(2) 2s^(2)2p^(3))` So `IE_(2)` of `O gt IE_(1)` of N.
