When the electronic configuration of any element is not the same as we expected, it is known as anomalous EC. For Eg Cromium, Copper and heavier d and f block elements.
An anomalous electron configuration in an atom can lead to unique behavior and properties. This can affect the atom's reactivity, stability, and ability to form chemical bonds. It may also impact the atom's energy levels and overall electronic structure, influencing its physical and chemical properties.
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 for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
The electron configuration for V3 is Ar 3d2.

A cation has a depleted electron configuration.
The electron configuration for beryllium, Be, is 1s22s2.
Cu has an anomalous electron configuration. Cu = 1s2 2s2 2p6 3s2 3p6 4s1 3d10, it does not follow the usual pattern. In this case, the 3d subshell is filled before the 4s, which usually happens in the reverse order (1s2 2s2 2p6 3s2 3p6 4s2 3d9).
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
The electron configuration of francium is [Rn]7s1.
Hydrogen electron configuration will be 1s1.
Uranium electron configuration: [Rn]5f36d17s2
