1. The problem statement, all variables and given/known data If electrons did not have intrinsic angular momentum, the states occupied by the electrons int he ground state of He would be a) (n=1, l=0) and (n=1, l=0) b) (n=1, l=0) and (n=1, l=1) c) (n=1, l=0) and (n=2, l=0) d) (n=2, l=0) and (n=2, l=1) e) (n=2, l=0) and (n=2, l=1) 3. The attempt at a solution From what I know, the intrinsic angular momentum for the ground state is limited to two electrons due to the exclusion princple. In this case, wouldnt the answer be a? He has only 2 electrons, and they are already in (n=1, l=0) and (n=1, l=0) (one spin up and one spin down).....right?
