Does Chromium and Copper Special Shell Rule Apply to other atoms?

Hey Guys,
For the electron configuration exceptions such as elements 24 and 29 are the exceptions only for these two elements or for all ions with 24 and 29 electrons such as Fe2+. Thanks in advance!!!!

Definitely beyond the scope of VCE Chemistry, but I do believe its only for those two specific atoms and not isoelectronic ions. Fe2+ has an electron configuration of 1s2 2s2 2p6 3s2 3p6 3d6; Cu and Cr are just exceptions that occur not so much as a result of only the number of electrons, but how the electrons also interact with the nucleus (number of protons).
