Melting and Boiling Point
Density
Colour

Hardness

Most of the metals are hard, except alkali metals, such as sodium, potassium, lithium, etc. are very soft metals. These can be cut by using a knife.

Strength

Most of the metals are strong and have high tensile strength. Because of this, big structures are made using metals, such as copper (Cu) and iron (Fe). (Except Sodium (Na) and potassium (K) which are soft metals).

State

Metals are solid at room temperature except for mercury (Hg).

Sound

Metals produce ringing sound, so, metals are called Sonorous. Sound of metals is also known as Metallic sound. This is the cause that metal wires are used in making musical instruments.

Malleability

Metals are malleable. This means metals can be beaten into a thin sheet. Because of this property, iron is used in making big ships.

Ductility

Metals are ductile. This means metals can be drawn into thin wire. Because of this property, a wire is made of metals.

Melting and Boiling Point

Metals have generally high melting and boiling points. (Except sodium and potassium metals which have low melting and boiling point.)

Density

Most of the metals have a high density.

Colour

Most of the metals are grey in colour. But gold and copper are exceptions.
