Question

what properties did you think of while categorising elements as metals or non metals?

Answer 1

electronegativity , intermolecular force of attraction, and its boiling point and melting point

Answer 2

Explanation:

NON - METALS --------

Malleability :- Non-metals cannot be made into thin sheets by hammering, i.e. they are not malleable.

Ductility :- Non-metals cannot be drawn into wires, i.e. they are not ductile.

Thermal conductivity:- Non-metals do not conduct heat, except diamond and graphite, allotropes of carbon, are good conductors of heat.
