All the atomic shells for the examined atoms are shown and the """"""""reasonable"""""""" electron numbers are given. Especially for atomic subshell and shell structure of transition elements are correctly predicated. This theory provides uniform and objective criterion for shell structure of isolated atom, and the intrinsic and theoretical basis for the shell structure given by other methods. This theory provides a kind of new method for describing the atomic shell structure.
