Spin angular momentum of an electron has no analogue in classical mechanics. Howerver, 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 ana tom 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 `=(2sums+1)` Q. Total spin of `Mn^(2+)(Z=25)` ion will be:
