Answer 2

Physical Material Properties of Non Metals

The physical properties of non – metals are :

The solid non-metals are brittle or dull and soft as they can be broken down into a powdery substance or mass on tapping down with the hammer.

Few examples are Coal and Sulphur.

However, Diamond is an exception as it is the hardest non-metal.

Non – metals may be either solids, liquids, or gases.

Non-metals are poor conductors of heat and electricity except Graphite.
They do not possess metallic luster.

Non-metals are not sonorous, they do not produce a ringing sound.
Non-metals possess no malleability.

They are not ductile.

They have dull luster, however, iodine is lustrous.

Some example of non – metals are carbon, oxygen, Sulphur, phosphorous, and many more.

Uses of Non Metals

Many non-metals like chlorine, Sulphur, iodine are very useful for medicinal purposes.

Non-metal like oxygen is very essential for our life for respiration.

We use nitrogen phosphorus in fertilizers for better plant growth and enhance the fertility of the soil.

Non-metal like Sulphur is useful in crackers.

Chlorine and Fluorine are useful for the water purification purpose.
