Question

The first iomsation energy of oxygen is smaller compased to nitrogen give reason​

Answer 1

Answer:

Hi there.

Explanation:

The reason is because of lesser atomic size of oxygen than nitrogen.

Answer 2

$\huge\sf\pink{Answer࿐}$

The first iomsation energy of oxygen is smaller compased to nitrogen because there are two electrons in the first orbital of the O sublevel, there is greater electronic repulsion in the 2p sublevel for O than N. Therefore, it is easier to remove an electron from the O than the N, and the ionization energy of O is lower than N.
