Fluorine is more reactive than chlorine.
Which statement explains this?
The outer shell of a fluorine atom is closer to the nucleus, so it gains an electron more easily.
A fluorine atom has fewer outer shell electrons, so it loses them more easily.
The outer shell of a fluorine atom is further from the nucleus, so it gains an electron more easily.
Fluorine molecules have weaker intermolecular forces, so they react more easily.
