The expected ground-state electron configuration of copper is ; however, the actual configuration is because a full dsubshell is particularly stable. There are 18 other anomalous elements for which the actual electron configuration is not what would be expected.
The electron configuration of 1s22s22p3s1 is not the ground state electron configuration of any element. This configuration contains 8 electrons, which in the ground state would be oxygen. The ground state configuration of oxygen is 1s22s22p4.
The ground state electron configuration of bromine is Ar 4s 3d 4p.
The ground-state electron configuration for the V3 ion is Ar 3d2.
The ground state electron configuration for iron (Fe) is Ar 3d6 4s2.
The ground state configuration of 1s²2s²2p²3s²3p¹ is [Ne]3s²3p¹. This notation represents the electron configuration in shorthand form, where [Ne] represents the electron configuration of the noble gas neon (1s²2s²2p⁶).
