Question: We have considered helium configurations in which only one electron is excited. Get a rough estimate of the energy of the 2s2 configuration from Eq.

We have considered helium configurations in which only one electron is excited. Get a rough estimate of the energy of the 2s2 configuration from Eq. (9.48). Compare this with the ground-state energy of the He+ ion to show that the 2s2 helium configuration is unstable with respect to ionization to He+ and an electron. If we had obtained a more accurate estimate of the 2s2 energy by including the first-order energy correction, would this increase or decrease our estimate of the 2s2 energy?
