Periodic variation of the properties of oxides of the elements of the third period

group 1 group 2 group 13 group 14 group 15 group 16 group 17

reaction of oxides with water and the acid-base character of hydroxides Na₂O gives NaOH (strong base) MgO gives

Mg(OH)₂ (weak base) Al₂O₃ nonreacting SiO₂ nonreacting P₄O₁₀ gives H₃PO₄ (weak acid) SO₃ gives H₂SO₄ (strong acid) Cl₂O₇ gives HClO₄ (strong acid)

bonding in oxides Na₂O ionic MgO ionic Al₂O₃

ionic SiO₂ covalent P₄O₁₀ covalent SO₃ covalent Cl₂O₇ covalent
