MgCl2 and Na2SO2
Answer:
MgCl₂ and Na₂SO₄ are the formula of magnesium chloride and sodium sulphate respectively.
Explanation:
1. Magnesium is a group two element. Hence it has two valence electrons in the outermost shell.
For magnesium chloride to be formed, two units of chlorine should combine with one unit of magnesium. Since the valency of chlorine is one.
Therefore, the formula of magnesium chloride is MgCl₂
2. The valency of sodium is one as it is a group one element. The charge on sulphate ion is -2.
Therefore, the formula of sodium sulphate is Na₂SO₄
