Pauli’s exclusion principle

Pauli’s exclusion principle: No two electrons in an atom can have the same value for the same set of four quantum numbers. Thus if two electrons have identical values of n ℓ and m it follows from this principle that they must differ in their spins i.e., +½ or -½. This means that two electrons can occupy the same sub-level and only if their spin are opposed. Natural…

De Broglie’s theory of wave nature of electrons

De Broglie’s theory of wave nature of electrons: Electron, like light has dual character (particle and wave like) de Broglie suggested the wave nature of electrons and derived the relation λ = h/p where λ is the wavelength and p the momentum of the electron and h is Plank’s constant. This relation is verified by interference and  diffraction experiments with electrons.
