. There actually are simple... F have higher electronegativity (4.0) than Cl. Electronegativity refers to the ability of an atom to attract shared electrons in a covalent bond.
There would be an equal amounts of ELECTRONS.
In order for the atom to be neutral it would imply that the number of protons (positive particles) and the number of electrons (negative particles) are equal since the neutrons are without charge.
B: produces energy for the cell
