Chemical Properties of Non-Metals

1. Reaction with Water

Non-metal does not react with water but it is usually very reactive in air, which is why some of them are stored in water. For example, one of the highly reactive non-metals is phosphorus and it catches fire when exposed to air that is why it is stored in water to prevent its contact with atmospheric oxygen.

2. Reaction with Acids

None of the non-metals is known to react with acids.

3.Reaction with Oxygen

Oxides of non-metals are formed when it reacts with oxygen. The oxides of non-metals are acidic or neutral in nature.

When sulphur reacts with oxygen, we get sulphur dioxide.

S + O2 → SO2

When sulphur dioxide reacts with water it forms sulphurous acid.

SO2 + H2O → H2SO3
