WebThe simplest example of Pauli exclusion principle is the helium atom, with two electrons in its 1s orbital. The first three quantum numbers are: n = 1, l = 0, and m l = 0. Therefore, the two electrons have spin quantum numbers: m s = +1/2 and m s = -1/2 [1-4]. Similarly, the electron spins of oxygen, fluorine, and neon are illustrated below. WebPauli’s Exclusion Principle. Pauli’s Exclusion Principle is derived by analysing the mathematics of quantum mechanics and applies to all matter. It states that no two electrons in an atom can have the same four quantum numbers. The electron has a spin that is always an integer, 0, 1/2, 1, 3/2, and so on.
