What is manganese electron configuration in long and short form?

In long form, the electron configuration of manganese (Mn), which has an atomic number of 25, is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁵. In short form, using the nearest noble gas (argon, Ar) as a reference, it can be written as [Ar] 4s² 3d⁵. This configuration indicates that manganese has two electrons in the 4s orbital and five electrons in the 3d subshell.
