The spin quantum number is a half-integer value that is either -1/2 (called "spin down") or 1/2 (called "spin up"). An atom consists of a large number of orbitals which are distinguished from each other on the basis of their shape, size and orientation in space. Its value is dependent on the angular momentum quantum number, l . Other articles where magnetic quantum number is discussed: spectroscopy: Angular momentum quantum numbers: There is a magnetic quantum number also associated with the angular momentum of the quantum state. Magnetic quantum numbers articulate the energy available in a subshell and estimate the orbital angular momentum along a specific axis. Magnetic Quantum Number.
