Q. What is the dissimilarity between Free Electron Theory and Band Theory of solids?
Answer:-
The Free Electron Theory
This theory notifies that metals conduct electricity because of the presence of free electrons in it. The farthest shells of metal atoms will be loosely bound with their nucleus. Therefore the electrons in it are free to move anywhere in the solid. These electrons are describe free electrons and they are responsible for the conduction of electricity.
