Ion(s)

Definition:

An ion is an atom or molecule that is not electrically neutral, but instead carries a positive or negative electrical charge, which is due to the loss or gain of one or more electrons.

An anion is a ion with a negative electrical charge, e.g. chloride (CI-), as opposed to a cation which is an ion with a positive electrical charge, e.g. sodium (Na+).
