A) write multi-electron atom. one of the excited electron configurations of the lit ion is down the configurations of the 4 states including spin that correspond to (1s)1(2p2)1. (b) write down the (antisymmetrized) wavefunctions of all 4 states in terms of the spatial and spin components, 5. starting from slater determinants and multiplying them out. (c) in each wavefunction, factor out the spatial and the spin parts if possible and determine whether those parts are symmetric or antisymmetric under electron exchange
