Question

compare the physical properties of non metal and metal with respect to the following:1.conduction of heat and electricity 2.malleability 3.ductility 4.lustre

Answer 1

hey mate

holaaa

here is the answer


PHYSICAL PROPERTIES OF METAL AND NON - METAL
1. Conduction of heat and electricity:

the heat is conducted by the metals , so metals are good conductor of heat

the heat is conducted by metals because

* the close packing of metal ions in lattice

* the delocalised electrons can carry kinetic energy through the lattice .

the electricity is also conducted by metals so , it is also a good conductor of electricity .

* electricity is conducted by metals because in metals there there are free electrons moving here and there and the protons are bound tightly with nucleus but the free electrons have no tight bond with nucleus and when we give some external force which is electrostatic force then the free electrons begins to move and then because of moving of electrons the electricity is produced..

Non - metals are generally bad conductors of both heat and electricity .

but there are some exception
like : graphite is good conductor of electricity but it is a non - metal.

2.Malleability: metals are generally malleable .
malleability is the property of matter to bend or change their shape without breaking.

metals are generally malleable .
like : iron , silver , gold etc .

non - metals are not malleable as the can break when we bend it

like : wood , etc.

3.Ductility : it is the property of metal to stretch into thin wires without being weak .

metals are ductile

like : copper , aluminium etc.

non - metals are not ductile

like : wood etc.

4.Lusture : it is the property of the metal or a substance to shine .

metals are generally lustrous
like : gold , silver etc.

non - metals are not lustrous

like : wood , plastic etc.

but some exception are there

like : diamond is very shiny but it is a non - metal.


hope it may help you
