Remember that metals react with oxygen in the air to produce metal oxides, like magnesium oxide.
Non-metals react with oxygen in the air to produce non-metal oxides. Here are two examples for the non-metals carbon and sulphur.
Carbon burns in air to form carbon dioxide:
carbon + oxygen → carbon dioxide
Sulphur burns in air to form sulphur dioxide:
sulphur + oxygen → sulphur dioxide
Non-metal oxides such as sulphur dioxide and nitrogen oxide are responsible for acid rain. They dissolve in the water in the clouds to form acidic solutions. Acid rain damages rocks and buildings, and harms wildlife.
Differences between metal oxides and non-metal oxides
There are some important differences between the physical and chemical properties of metal oxides and non-metal oxides. The table shows some of these differences.

Metal oxides are basic in nature they react with acids to form salt whereas non-metal oxides are acidic in nature they react with bases to form salt
