✰Answer✰

⋄ The physical properties of non metals are:-

➧ Non -Metal do not possess any Lustre .( except iodine which is non-metallic solid but has lustre )

➧ They are soft and brittle, i.e. the break into pieces when hammered. The only exception is that of diamond allotropic form of carbon which is known as the non metal but it is the hardest substance.

➧ They are not malleable.

➧ They are bad conductor of heat and electricity. (except graphite which is an allotropic form of carbon and is non metal but a good conductor of electricity and is used in making electrodes.) This is due to absence of free electrons in them except graphite which has free electrons.

➧ They are non sonorous, i.e., they do not produce any sound when hit with hard object.

➧They generally have low melting and boiling points .(except Boron, diamond and graphite which are non metal but have a high melting points)

➧ They have low tensile strength, i.e.,they easily broken.

➧ They may be solid, liquid or gas at room temperature. For example carbon Sulphur , Phosphorus and Iodine are solid non-metals Bromine is liquid non-metal while hydrogen oxygen nitrogen and chlorine are gaseous non metals.
