write note on free electron theory
Electronic theory is the theory of the behavior of the electron under various conditions including a free electron, a bound electron in either an outer or inner orbit of the atom.
Lee De Forest invented the electron tube in 1906.

Nobody "invented" the electron cloud. The concept was discovered by Werner Heisenberg in 1926.
the same way an insulator and a conductor will work with out the electron theory!
Its the Lewis Theory He also made the theory about the electron dot structures
There is no single unified theory that explains all correlated electron systems.
1608 was when the Microscope was invented.
Classical free electron theory could not explain many physical properties. In 1928, Sommerfeld developed a new theory applying quantum mechanical concepts and Fermi-Dirac statistics to the free electrons in the metal. This theory is called quantum free electron theory.
