1/ ENERGY BANDS IN SOLIDS In this chapter we begin with a review of the basic atomic properties of matter leading to discrete electronic energy levels in atoms. We find that these energy levels are spread into energy bands in a crystal. This band structure allows us to distinguish between an insulator, a semiconductor, and a metal. 1-1 CHARGED PARTICLES The charge, or quantity, of negative electricity and the mass of the electron have been found to be 1.60 X 10- 19 C (coulomb) and 9.11

Metabolism is the mechanism whereby the body converts food into different forms of energy by digesting food in the presence of oxygen. This energy takes the following forms: 1. Work 2. Thermal Energy 3. Waste products Work The amount of bodily energy converted into work is not very great - 0% for a body at rest, 20% when walking up a one in four gradient at 10km/h. Thermal Energy Most of the energy produced by the bodily metabolism is dissipated as heat to the environment
