Pauli Exclusion Principle.
Map content
Pauli Exclusion Principle.
is the quantum mechanical principle that says that two identical fermions (which are particles with half-integer spin) cannot occupy the same quantum state simultaneously.
- In the case of electrons is different , here it says that:it is impossible for two electrons of a poly-electron atom to have the same values of the four quantum numbers (n, ℓ, mℓ and ms)
- For two electrons residing in the same orbital, n, ℓ, and mℓ are the same, so ms must be different and the electrons have opposite spins.
- For two electrons residing in the same orbital, n, ℓ, and mℓ are the same, so ms must be different and the electrons have opposite spins.
- In the case of electrons is different , here it says that:it is impossible for two electrons of a poly-electron atom to have the same values of the four quantum numbers (n, ℓ, mℓ and ms)
this theory was formulated by Austrian physicist Wolfgang Pauli in 1925.
