Question

The correct ground state electronic configuration of chromium atom of (Z=24) IS​

Answer 1

Answer:

• Electronic configuration of Cr atom is 1s2,2s2p6,3s2p6d5,4s1. This is because an electronic configuration with half-filled and completely filled orbitals is more stable. 24Cr has 3d orbitals half-filled which is more stable configuration than normally expected i.e., 3d44s2.
