Describe the classic model for electrical conduction in metals.

Expert Solution & Answer

To determine

The description of the classic model for electrical conduction in metals.

Explanation of Solution

In metals, the arrangement of the atoms in the crystal structure is kept together with the metallic bonds that make it possible the movement of valance electrons. In the classic model of the electrical conductivity of a metal, the valance electrons present at the outermost layer are assumed to freely displace between the cores of positive ions in the lattice. Having some kinetic energy at the room temperature, the cores of positive ions vibrate in their lattice positions; however, with the rise in temperature the intensity of the vibrations rise and interchange of energies between electrons and the cores occurs. The electrons vibrate without any electric potential and randomly moves producing no current flow. But when a potential difference is applied, the electrons begin to travel uniformly by producing electric currents.
