An ANION is aan ION with a negative charge.

Common anions are Cl^(-) (Chloride) , O^(2-) ( Oxide)

Compare with

CATION which is an ion with a Positive charge.

Common cations are Na^(+) Sodium , Ca^(2+) Calcium .

NB An atom that gains or loses electrons to become a charged species, is no longer an atoms ,but an ION.
