Question

Distinguish between metals and non –metals with respect to their lustre, malleability, ductility and conductivity.

Answer 1

1.Metals are malleable which means that they can be beaten to thin sheets whereas non-metals are non malleable.
2.Metals are ductile whereas non metals are not. 
3.While metals are good conductors of electricity and heat, non-metals are poor conductors.
4.Metals have a metallic luster whereas non metals do not.

Answer 2

1)they are lustrous.
2)they are malleable
3) they are ductile
4)they are good conductors of heat and electricity.

=============================
