Question

Anion & Cation

Open in App

Solution

Cations are ions with a net positive charge.

Cation Examples: Silver: Ag⁺, hydronium: H₃O⁺, and ammonium: NH₄⁺

Anions are ions with a net negative charge.

Anion Examples: hydroxide anion: OH^-, oxide anion: O^2-, and sulfate anion: SO₄^2-

Because they have opposite electrical charges, cations and anions are attracted to each other. Cations repel other cations, while anions repel other anions.
