how can we find the angular momentum , spin angular momentum and magnetic moment of electron?

Dear Tarun,

 Angular momentum of electron in a given stationary state is ,        L = nh/2Π   here n =1,2,3....

                                                                                                                               h = plancks constant

Spin Angular momentum of electron is ,       S = sqrt.[s(s+1)]*h/2Π

 spin '?s'? can have values of +½ or ?-½,

Magnetic Moment of electron is,        μ = sqrt.[n(n+2)]    , here, n = no. of unpaired electrons and  its unit is BM - Bohr magnetron
