There is yet another way to writing electron configurations. d) 2d What is the significance of the #3d_(x^2-y^2)# atomic orbital? Two electrons fill the 1s orbital, and the third electron then fills the 2s orbital. There is a major exception to the normal order of electron configuration at Cr (#24) and Cu (#29). Electrons will fill orbitals in a specific order. These shells, in turn, have orbitals — regions of the shell where electrons inhabit. Now, let’s look at a cross-section of these orbitals. The subshells are much more closely spaced in energy and the exact electronic configurations are not so clear-cut: this is already evident within the d- and f-blocks where some anomalies are present. orbitals. The f-orbitals are unusual in that there are two sets of orbitals in common use.Those shown here are the cubic set and these are appropriate to use if the atom is in a cubic environment, for instance.
