Question
Chapter 21, Problem 21.62SP
Interpretation Introduction
Interpretation:
From the given data, the MO energy level diagrams has to be drawn. Also the one which agrees beryllium with high electrical conductivity has to be identified and explained.
Concept introduction:
- When the energy band is partially filled electrons can move from one level to another with applied electric potential.
- When the energy band is completely filled, then there is no vacant energy level and electron population remains same even applying electrical potential.
- Hence, materials known as electrical insulators have completely filled energy band. And materials known as conductors have partially filled energy band.
