Question 9

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

Answer

Metallic solids are electrical conductors, malleable, and ductile. They consists of an assemblage of positive ions (kernels) immersed in a ‘sea’ of mobile electrons. Thus, each electron belongs to a number of positive ions and each positive ion belongs to a number of electrons. The force that binds a metal ion to a number of electrons within its sphere of influence is known as metallic bond. This force of attraction is sufficiently strong and is thus responsible for compact solid structure of metals and therefore these solids are good conductors, malleable and ductile in nature. For example metals like copper, nickel etc.
