Ions are created when a neutral atom loses or gains electrons.

Ions are created when atoms lose or gain electrons
To remind you, here’s an image of electronic robots (electrons) playing a round of golf using golf irons (ions).

An ion is an atom or molecule that carries an electric charge.

Ions are identified with the sign and size of their charge.

Negatively charged ions are called anions.

Positively charged ions are called cations.

Examples of anions:

Br = Bromine atom which has gained an electron

N³⁻ = Nitrogen atom which has gained 3 electrons

Examples of cations:

Na = Sodium atom which has lost an electron

Fe³⁺ = Iron atom which has lost 3 electrons
