• Sodium ion (Na+)

• Nitrogen ion (N-)

• Chloride ion (Cl-)

How are cations formed?

• By losing electrons

• By gaining electrons

• By sharing electrons

• By becoming neutral

How are anions formed?

• Atoms gain electrons to form anions.

• Atoms lose electrons to form anions.

• Anions are created by splitting molecules.

• Anions are formed by combining two atoms.
