1: Part A: Two electrons occupy the 2s shell in a Be atom (Z = 4). What are the possible quantum numbers J for the total angular momentum of this two-electron system, neglecting any contributions from the nucleus or 1s level?
Part B: Calculate the energy required to cause an electron from the 2s shell to jump to each of the 2p, 3s, 3p, and 3d states. E1 for Be is 9.3 eV. En = (-Z2E1)/n2. One of the listed states is not allowed. Which state is not allowed and why?
