Summary

Metals have the same characteristics, behaviour and properties. Some are that; they easily allow heat and electricity to pass through them.

They are not easily melted and are usually hard solids at normal room temperature except the metal mercury.

They are usually heavy.

Non-metals have characteristics and properties that are opposite of metals. Some are that; they do not allow heat and electricity to pass through them. They break easily (i.e are brittle).

They are soft and can easily be melted. They are usually not heavy.

Some elements are metals whiles others are non-metals.

Gold, Aluminium and Silver are elements that are metals.

Carbon is an element that is a non-metal.

Elements have been arranged in an orderly manner on a table called the periodic table based on whether they are metals or non-metals

An alloy is a mixture of two or more different metals or a mixture of a metal and non-metal

Bronze is an alloy made up of copper and tin. It is used to make coins and statues.

Corrosion takes place in metals that are easily attacked by air, water or chemicals and this makes them reactive. Examples of such metals are copper and zinc.
Meanwhile, other metals are not easily attacked by or do not combine with air, water or chemicals. These metals are non-reactive, examples are gold and silver.
Rusting is a special type of corrosion that takes place only in irons. Metals corrode but it is only irons that rust.
Rusting could be prevented by methods that cover the surface of the metal.
