Azimuthal quantum number  (l): it desiibes the shape of electron cloud and the number  of sub- shells in a shell .  it can have values from 0 to (n-1)    `{:("value of l","subshell"),(0,s),(1,p),(2,d),(3,f):}` Number of obitals  in a subsjhell = 2l +1   Orbital angular momentum `L=(h)/(2 pi)sqrt(l(l+1))`    `hsqrt(l(l+1))"              " [h=(h)/(2pi)]` magb=netic quantum number (m) :   it desicribes the orientations of the orbitals .It can have  values from -l to + l including zerop i.e total (2l+1) values . Each value corresponds to an ot=rbital  s- subshell has one orbital ,p - subshell three orbitals `(P_(x),P_(y)andP_(z))` d- subshell five orbitals `(D_(yz),d_(yz),d_(zx), d_(x^(2)-y^(2)),d_(z^(2))` and f- subshelll has seven orbtials .    Spin  quantum number (s) :   It  desiibes the spin of the electron , it has values `+(1)/(2)` and  `-(1)/(2)` Signifies  clock wise spining and anticlock wise  rotion of electron about its Own axis .  Spin of the electron produes spin angluar momentum equal to    `S=sqrt(s(s+1))(h)/(2pi), "where" s= +(1)/(2)`    total  of the  an atom `=+(n)/(2) or -(n)/(2)`   WHere n is the number  of unpaired  electron  s .   the magnetic moment of an atom    `mu_(s)=sqrt(n(n+2))B.M`   n- number  of unpaired electron s   B.M (Bohr magenton)    Magnetic moment of `""_(26)Fe^(2+)` ion is same  as :
