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 & each positive ion belongs to a number of electronsThe 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 & is thus responsible for compact solid structure of metals & therefore these solids are good conductors,malleable & ductile in nature.For eg metals like copper, nickel etc.
