What type of solids are electrical conductors, malleable and ductile?

Explanation

Metallic solids are electrical conductors, malleable and ductile in nature. Metals are electrical conductors because of the presence of free and mobile electrons in their crystal structures. Metals are found to be malleable because when they are beaten by the hammer, they are converted into thin sheets.
Metals are ductile because when they are drawn through a die, they are converted into thin wires. In both case of malleability and ductility, the crystal structures of metals remain the same.
