Metals vs Nonmetals - Difference and Comparison

Metals versus Nonmetals comparison chart
	Metals	Nonmetals
Physical state	Metals are solids at room temperature (except mercury).	Non-metals exist in all three states.
Conductivity	Metals conduct heat and electricity.	Non-metals do not conduct heat and electricity (except graphite, which conducts electricity).
Hardness	Most of the metals are hard and have high tensile strength except lithium, sodium and potassium.	Non-metals are usually soft (except diamond).
Luster	Metals possess a bright metallic luster.	Non-metals usually have dull appearance except iodine.
Malleability and ductility	Metals are usually malleable and ductile.	Non-metals are not malleable and ductile.
Melting point	Metals have high melting point except caesium and gallium.	Non-metals have low melting point.
Boiling point	Metals have high boiling point	Non metals have low boiling point
Sonorous	Metals are sonorous.	Non metals are non sonorous.
Ductility	Ductile	Non-Ductile
Malleability	Malleable	Non-Malleable
