The statement which is true is

Fluorine is more reactive than nitrogen because fluorine needs only one electron to fill its outermost shell.

<u><em>Explanation</em></u>

Fluorine has electron configuration of 1S²2S²2P⁵ while nitrogen has 1S²2S²2P³ electron configuration.

The 2P sub shell for nitrogen is half filled therefore it is sable than fluorine.

since p orbital can hold a maximum of 6 electrons ,Fluorine requires 1 electron to completely fill it's 2P sub shell which make it more reactive than nitrogen.
