Chemical properties of Metals and Non- metals:
Chemical properties of metals and non-metals can be divided into five categories: reaction with oxygen, reaction with water, reaction with acids, reaction with bases, and displacement reactions.
Reaction with Oxygen:
Metals
most metals combine with oxygen to form metal oxides.
Sodium reacts vigorously with the oxygen present in air to form sodium oxide. As a result, it catches fire if left in open. It is, therefore, kept immersed in kerosene.
Magnesium, on heating, burns in air (oxygen) with a dazzling white light to form magnesium oxide.
Amphoteric Oxides:
The metallic oxides formed are basic in nature and turn red litmus solution blue but their are some oxides which show both acidic and basic behaviour i.e. react with both acid and base. One of the example of amphoteric oxide is Aluminium oxide. It reacts with acids and base as follows:
