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.
Hooke's law (R. Hooke): The stress applied on any solid is proportional to the strain it generates in the elastic limit for that solid. The constant of that proportionality is
The set of rectangular axes obeying the Newton's laws of motion and used to describe the position of a particle or an event are known as inertial frames of reference.
Alloying: When an impurity atom of a different size compared to the host atom is placed into the crystal lattice, the impurity atom distorts the resin around it, either by pushing
