Non-Metals
Any substance that is NOT a metal is classified as a non-metal. There are:
(i) NON-METAL ELEMENTS, e.g. chlorine, carbon, sulphur and carbon and oxygen
(ii) NON-METAL COMPOUNDS, e.g. sulphur dioxide, ammonia and nitric acid.

Chemical properties
Non-metals are able to receive electrons from METALS. They do this to fill their Outer shell. When a non-metal receives/gains electrons, the number of electrons are now more than the number of protons, thus making the non-metals NEGATIVELY charged. They are now called ANIONS. The type of compound formed is said to be IONIC.
The following document highlights some fo the chemical properties of non-metals.
