WebThe first excited state in Helium is 1s12s1(1 electron is excited to the lowest empty orbital which is 2s here). If 1 electron has an up-spin and the other one has a down-spin, their spin components are eliminating each other (Total Spin = 1/2 + (-1/2) = 0). The Fomulae 2S+1 gives the n-let formalism.
