Any five metals and non metals …

Metals - Sodium, potassium, magnesium, aluminium and copper.

Non-metals - Carbon, hydrogen, sulphur, nitrogen and chlorine.

Physical Properties of Metals:

1. Physical State: All metals are solids at room temperature.

Exceptions: Mercury and gallium are liquids at room temperature.

1. Lustre: All metals in their pure state have a shine and can be polished to give a highly reflective surface.
2. Malleability: Metals  have  the  ability  to  withstand  high  tensile  strength  and  can  be  made  into  thin  sheets.  This property of metals is called malleability.

Physical Properties of Non-Metals:

1. Non-metals are either in the solid or gaseous state.

Exception: Bromine is an exception which exists in the liquid state.

1. Non-metals do not have lustre.

Exception: Iodine crystals are lustrous.

Chemical Properties of Metals:

1. Reaction of Metals with Oxygen: Almost all metals react with oxygen to form metal oxides.

Metal  +  Oxygen → Metal oxide

ii. Reaction of Metals with Water: Metals react  with  water to produce metal oxides with the release of hydrogen gas. But all metals do not react with water.

Metal +  Water → Metal oxide + Hydrogen
