Chromium (Cr) Electron Configuration

Chromium has 24 electrons with an electron configuration of 2,8,13,1. This is an unique case where one electron jump from the 4s orbital to the 3d orbital to enhance stability. The reason for this is because half-filled orbitals are equally stable as completely filled orbitals. Note that the d-orbital holds a maximum of 10 electrons. Therefore, having 5 electrons (half of the total), is as equally stable as having 10 electrons.

This is wrong electronics configuration
