A metal and a non metal or negative polyatomic ion.

Explanation:

Ionic bonds are formed between particles that have a large difference in electronegativity

Metals have a low electronegativity which makes them the ideal cation for the formation of an ionic bond.

Non metals like Chlorine, and sulfur have high electronegativity which when combined with a metal atom with a low electronegativity forms an ionic bond.

Polyatomic ions like Nitrate # ( NO_3^-1)# have resonance structures that make separation of the charges easily.
