What is the difference among Free Electron Theory and Band Theory of solids?
Free Electron Theory:
This theory says that, metals conduct electricity due to the presence of free electrons in it. The outermost shells of metal atoms will be loosely bound with their nucleus. So the electrons in it are free to move anywhere in the solid.
These electrons are known as free electrons and these electrons are responsible for the conduction of electricity.
