WebTo understand electrical properties of solids, we need to use Band theory. In this video, we will explore this new theory called Band theory. We will understand step by step how the discrete energy levels of electrons evolve into an energy continuum called bands in solids. Created by Mahesh Shenoy. WebState the five basic assumptions of the kinetic-molecular theory. 1.Gases consist of large numbers of tiny particles that are far apart relative to their size. 2. Collisions between gas particles and between particles and container walls are elastic collisions. 3. Gas particles are in continuous, rapid, random motion.

In solid-state physics, the electronic band structure (or simply band structure) of a solid describes the range of energy levels that electrons may have within it, as well as the ranges of energy that they may not have (called band gaps or forbidden bands). Band theory derives these bands and band gaps by examining the allowed quantum mechanical wave functions for an electron in a large, periodic lattice of atoms or molecules.
