What is the electron configuration for a sodium ion? Anomalous electron configurations Some atoms, such as some transition metals and some elements in the lanthiinide and actinide series, do not adhere strictly to Hund's rule and Paul's principle. Hund's rule asserts that even if multiple orbitals of the same energy are available, electrons fill unoccupied orbitals first, before reusing orbitals occupied by other electrons. Six of these are listed on the table below. Parabolic, suborbital and ballistic trajectories all follow elliptic paths. In the case of copper, silver and gold, an electron from the highest-occupied s orbital moves into the d orbitals, thus filling the d subshell.
