Question

The spin quantum number is denoted by ________.

• A. $\text{n}$
• B. $\text{l}$
• C. ${\text{m}}_{\text{s}}$
• D. ${\text{m}}_{\text{l}}$

Answer 1

The correct option is C ${\text{m}}_{\text{s}}$

The spin quantum number represents the spin of the electrons in an atom. It is denoted by "${\text{m}}_{\text{s}}$". It indicates the two possible orientations of the spin of an electron, one clockwise spin $(+\frac{1}{2})$ and other anti-clock wise spin $(-\frac{1}{2})$.
