Question

Give three differences between metals and
non-metals. follow me guys will follow you want the accurate answer​

Answer 1

On the basis of physical properties :-

Metals:

1. All metals are solid at room temperature except mercury, which is a liquid at room temperature.
2. All metals are lustrous.
3. Metals have high densities except lithium, sodium and potassium.
4. Metals are malleable (can be beaten into thin sheets).
5. Metals are ductile (can be drawn into wires).
6. They are good conductors of heat and electricity.
7. They have high melting point.

Non-metals:

1. Exists as solid, liquid and gas.  Silicon is a solid, bromine is a liquid and oxygen is a gas.
2. Non-metals are non-lustrous.
3. They have a low density.
4. They are non-malleable.
5. They have low melting and boiling point.
6. They are poor conductors of heat and electricity.
7. They are non-ductile.

On the basis of chemical properties:-

Metals:

1. Metals react with non-metals to form ionic compounds.  eg:- 2Na + Cl₂ -->  2NaCl
2. Metals combine with oxygen to form metal oxides which are basic in nature.  eg:- 2Mg + O₂ → 2MgO

Non-metals:

1. Non-metals form covalent bonds.
2. Non-metals dissolve in water to form acidic solutions.  eg:- SO₂ + H₂O → H₂SO₃

Answer 2

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
