The electronic configuration for sodium is 1s2 2s2 2p6 3s1, and the electronic configuration for potassium is 1s2 2s2 2p6 3s2 3p6 4s1. It requires 5.1 eV to remove the outermost electron (3s1) from sodium. What can you say about the energy required to remove the outermost electron from potassium (4s1)? Since each is the outermost electron around the atom, the energy required will be equal to 5.1 eV. Since each electron is in an s orbital, the energy required...
