Physical properties of metals and non-metals
Hardness
Metals are generally hard
Non-metals soft and brittle (break when hammered). Carbon (diamond) is the hardest substance
Melting and boiling point
Metals have generally high melting and boiling point - Cesium 28 C
Non-metals have low melting and boiling point - Diamond 3723 C
Conductivity
Metals are good conductors of heat and electricity
Non-metals are poor conductors of heat and electricity. Carbon (Graphite) a non-metal is good conductor of electricity
Ductility
Metals can be drawn into thin wires
Non-metals cannot be drawn into thin wires.
Malleability
Metals are malleable - can be hammered into thin sheets
Non-metals are non-malleable
Lustre
Metals have lustre (They shine)
Non-metals are non-lustrous - Iodine has lustre
Sonorosity
Metals produce ringing sound
Non-metals are non-sonorous
Physical State
Metals are solids in general (There are exceptions - Mercury)
Non-metals exist in all the three forms viz., solids, liquids and gases
Density
Metals have high density
Non-metals have low density
Tensile Strength
Metals have high tensile strength
Non-metals do not have high tensile strength. Carbon fibre (rope) has high tensile strength
