Less than that of pure metal.

Vedclass · Answer

(D) An alloy is a homogeneous mixture of two or more metals or a metal and a non-metal.When an alloy is formed,the regular arrangement of atoms in the pure metal lattice is disrupted by the addition of other atoms.This disruption hinders the movement of free electrons,which are responsible for electrical conduction,thereby decreasing the electrical conductivity compared to the pure metal.Additionally,the presence of foreign atoms creates lattice distortions that require more energy to overcome during the phase transition from solid to liquid,which typically results in a lower melting point compared to the pure metal (though this can vary,the general property of alloys is lower conductivity and lower melting point than the base metal).

The electrical conductivity and melting point of an alloy is:
