define spin quantum number?

Answer 1

Answer:

Spin Quantum Number

Explanation:

The spin quantum number is the fourth quantum number, denoted by s or ms. The spin quantum number indicates the orientation of the intrinsic angular momentum of an electron in an atom. It describes the quantum state of an electron, including its energy, orbital shape, and orbital orientation.

The Spin Quantum Number (m s) describes the angular momentum of an electron. An electron spins around an axis and has both angular momentum and orbital angular momentum. Because angular momentum is a vector, the Spin Quantum Number (s) has both a magnitude (1/2) and direction (+ or -). Each orbital can only hold two electrons.

Electron spin is denoted by a symbol ‘s’ and the electron spin quantum number is denoted by a symbol ‘ms’. The Electron spin, 's' has only 1 possible value. That value is ½ (one by two). Like the electron's rest mass and charge, spin does not differ.
