On the basis of physical properties :-
Metals:
- All metals are solid at room temperature except mercury, which is a liquid at room temperature.
- All metals are lustrous.
- Metals have high densities except lithium, sodium and potassium.
- Metals are malleable (can be beaten into thin sheets).
- Metals are ductile (can be drawn into wires).
- They are good conductors of heat and electricity.
- They have high melting point.
Non-metals:
- Exists as solid, liquid and gas. Silicon is a solid, bromine is a liquid and oxygen is a gas.
- Non-metals are non-lustrous.
- They have a low density.
- They are non-malleable.
- They have low melting and boiling point.
- They are poor conductors of heat and electricity.
- They are non-ductile.
On the basis of chemical properties:-
Metals:
- Metals react with non-metals to form ionic compounds. eg:- 2Na + Cl₂ --> 2NaCl
- Metals combine with oxygen to form metal oxides which are basic in nature. eg:- 2Mg + O₂ → 2MgO
Non-metals:
- Non-metals form covalent bonds.
- Non-metals dissolve in water to form acidic solutions. eg:- SO₂ + H₂O → H₂SO₃

Answer:
Metals are good conducters of heat and electricity.
Non - metals are poor conductors of heat and electricity.
Metals have high melting and boiling points.
Non - metals have low melting and boiling points.
Metals are hard and strong.
Non -metals are soft and weak (except carbon).
Metals are usually found in solid states.
Non - metals are found in all the states.
Metals = example Iron Aluminium
Non metals = nitrogen oxygen
