Metal oxides

  • If a metal reacts with oxygen it will form a metal oxide.
    • Metal + oxygen → metal oxide
    • Iron + oxygen → iron oxide
    • Magnesium + oxygen → magnesium oxide
  • Metal oxides are alkaline.
  • Metal oxides are solids at room temperature.

Non-metal oxides

  • If a non-metal reacts with oxygen it will form a non-metal oxide.
    • Non-metal + oxygen → non-metal oxide
    • Carbon + oxygen → carbon dioxide
    • Sulfur + oxygen → sulfur dioxide
      • Sulfur dioxide dissolves in water in the clouds to form acid rain.
  • Non-metal oxides are acidic.
  • Non-metal oxides are gases at room temperature.
