It makes no difference to the physical laws, which only care that the charges are different. For example: the force between two negative charges is repulsive. So if you want to define “apart” as positive then two negatives (charges) makes a positive (force).

1. negative charge – having a surplus of electrons; having a lower electric potential. electric charge, charge – the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons; “the battery needed a fresh charge”

Atoms are made up of protons, neutrons, and electrons. Neutrons are neutral and do not have any charge at all. Protons carry a positive charge, and electrons carry the negative charge.

Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite.

An ion is a charged particle formed when an atom , or a group of atoms, loses or gains electrons ….Chemical formulae of ions.

An anion has more electrons than protons, consequently giving it a net negative charge. For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them.

5 Answers. From Wiki: Faraday also introduced the words anion for a negatively charged ion, and cation for a positively charged one. Since the Anode is positively doped, it will attract electrons from the cathode, and this will cause the formation of Anions in its side of the depletion region.

: the ion in an electrolyzed solution that migrates to the anode broadly : a negatively charged ion.
