Na⁺,SO₄²⁻

Explanation:

Sodium sulfate is formed by the sodium and sulfate ion.

Sodium is present in group one thus it has only one valence electron. Sodium lose its one valence electron to get complete octet and thus form cation with +1 charge.

On other hand sulfate ion is an anion it carries -2 charge so when it react with sodium there are two sodium atom combine with one sulfate ion inorder to make the compound neutral.

2Na + SO₄²⁻  →  Na₂SO₄

Sodium sulfate is actually form when sodium react with sulfuric acid and hydrogen gas is liberated.

Chemical equation:

Na + H₂SO₄  →  Na₂SO₄ + H₂

Balance chemical equation:

2Na + H₂SO₄  →  Na₂SO₄ + H₂
