Question

Why fluroine is more reactive than chlorine?
​

Answer 1

Answer:

Chlorine is less reactive than fluorine because the outer electrons in a chlorine atom are further from the nucleus than the outer electrons in a fluorine atom. It is harder for a chlorine atom to gain an electron than it is for a fluorine atom

pls follow me

Answer 2

ANSWER

The electronic configuration of fluorine is ---- 2,7 (only two shells)

The electronic configuration of chlorine is---- 2,8,7 (three shells)

Thus, the Fluorine has more tendency to gain electrons due to more charge with the nucleus (due to less shells), thus it is more electronegative than chlorine and thus it is more reactive or reacts more easily in gaining electrons from other atoms.

hope it helps ☺️
