An electron state has spin number s = 1 / 2 , consequently m s will be + 1 / 2 ("spin up") or - 1 / 2 "spin down" states. Since electron are fermions they obey the Pauli exclusion principle: each electron state must have different quantum numbers. Therefore, every orbital will be occupied with at most two electrons, one ...
For an electron, s is 1 ⁄ 2, and m s is either + 1 ⁄ 2 or − 1 ⁄ 2, often called "spin-up" and "spin-down", or α and β. [ 1 ] [ 2 ] The term magnetic in the name refers to the magnetic dipole moment associated with each type of angular momentum, so states having different magnetic quantum numbers shift in energy in a magnetic field ...

[1] [2] The value of m s is the component of spin angular momentum, in units of the reduced Planck constant ħ, parallel to a given direction (conventionally labelled the z –axis). It can take values ranging from + s to − s in integer increments. For an electron, m s can be either + + 1 / 2 or − + 1 / 2 .
Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [1] [2]: 183–184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory.
[1] Good quantum numbers are often used to label initial and final states in experiments. For example, in particle colliders: [citation needed] Particles are initially prepared in approximate momentum eigenstates; the particle momentum being a good quantum number for non-interacting particles. The particles are made to collide.
The word quantum is the neuter singular of the Latin interrogative adjective quantus, meaning "how much"."Quanta", the neuter plural, short for "quanta of electricity" (electrons), was used in a 1902 article on the photoelectric effect by Philipp Lenard, who credited Hermann von Helmholtz for using the word in the area of electricity.
