Unformatted text preview: (lowest energy state) of a particular atom. The ground state configuration for oxygen, for instance, can be written as : This means that the lowest energy configuration of oxygen, with 8 electrons, is to have two electrons in the n=1 s-subshell, two in the n=2 s-subshell, and four in the n=2 p-subshell. Potassium (Z = 19) has an interesting ground state configuration: That's interesting because there is a d-subshell in the n = 3 shell, but instead of the last electron going into that subshell it goes into the s-subshell of the n=4 shell. It does this to minimize the energy: the 4s subshell is at a lower energy than the 3d subshell....
