Metals

Non-metals

Are bright shiny and can be pushed

Are usually dull

Have high melting and boiling points

Have low melting and boiling points

Are strong and can be hammered into thin sheets (are malleable)

Are not malleable

Are good conductors of heat and electricity

Are poor conductor of heat and electricity

Have very high densities

Have low densities

Are sonorous (make a sound when hit)

Are not sonorous

Are mostly solids at room temperature and pressure. Mercury is the only liquid.

Are mostly solids or gas ( bromine is the only liquid)

Are ductile (can be drawn into wire). Eg: metals, zinc, iron, aluminum, etc.

Are not ductile. Eg: oxygen, hydrogen, sulphur.

Mixture

Compounds

Composition, properties and appearances are not uniform.

Composition, properties and appearance and uniform

Constituents can be separated by physical means

Constituents cannot be separated by physical means

The properties are the average properties of the constituents

The properties are different from the properties of the constituents.
