Answer:
METALS
All metals are lustrous.
Metals have high densities except lithium, soduim and potassium.
Metals are malleable.
Metals are ductile.
They are good conductors of heat and electricity.
They have high melting point.
NON-METALS
Non-metals are non-lustrous.
They have low density.
They are non-malleable.
They are non-ductile.
They are poor conductors of heat and electricity.
They have low melting and boiling point.
