What happens when Fluorine atom reacts with a chlorine atom?

Answer 1

Chlorine and Fluorine generally do not react with each other, because they are in the same family, but they do form a highly reactive mixture. If the atoms happen to combine, I would assume you would get a Chlorine Monofluoride molecule, because chlorine and fluorine both have 7 valance eletrons, so they might share one, and it would look like this

Cl-F

they would share an electron, like F2, or Cl2 do.

Answer 2

When a fluorine atom reacts with a chlorine atom, they form a diatomic molecule called chlorine monofluoride (ClF). This reaction results in the sharing of electrons between the two atoms to achieve a stable octet configuration, with chlorine providing one electron and fluorine providing seven electrons.
