Spin angular momentum of an electron has no analog in classical mechanics. However, it turns out that the treatment of spin angular momentum is closely analogous to the treatment of orbital angular momentum.
Spin angular momentum `= sqrt(s(s+1)h)`
Orbital angular momentum `= sqrt(l(l+1)h)`
Total spin of an atom or ion is a multiple of `(1)/(2)`. Spin multiplicity is a factor to confirm the electronic configuration of an atom or ion.
Spin multiplicity `(2 sum s +1)`
In any subshell, the maximum number of electrons having same value of spin quantum number is :

Options

A. `sqrt(l(l+1))`
B. l+2
C. 2l+1
D. 4l+2

Answer

C
