The phrase spin quantum number refers to quantized spin angular momentum. The symbol s is used for the spin quantum number, and m s is described as the spin magnetic quantum number [3] or as the z-component of spin s z. [4] Both the total spin and the z-component of spin are quantized, leading to two quantum numbers spin and spin magnet quantum ...
These are indicated by assigning the particle a spin quantum number. [2]: 183–184 The SI units of spin are the same as classical angular momentum (i.e., N·m·s, J·s, or kg·m 2 ·s −1). In quantum mechanics, angular momentum and spin angular momentum take discrete values proportional to the Planck constant.
S is the total spin quantum number for the atom's electrons. The value 2S + 1 written in the term symbol is the spin multiplicity, which is the number of possible values of the spin magnetic quantum number M S for a given spin S. J is the total angular momentum quantum number for the atom's electrons. J has a value in the range from |L − S ...
In quantum physics and chemistry, quantum numbers are quantities that characterize the possible states of the system. To fully specify the state of the electron in a hydrogen atom, four quantum numbers are needed. The traditional set of quantum numbers includes the principal, azimuthal, magnetic, and spin quantum numbers. To describe other ...
The spin magnetic quantum number m s specifies the z-axis component of the spin angular momentum for a particle having spin quantum number s. 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.

Therefore, the term with lowest energy is also the term with maximum and maximum number of unpaired electrons with equal spin angular momentum (either +1/2 or -1/2). For a given multiplicity, the term with the largest value of the total orbital angular momentum quantum number has the lowest energy.
