The correct ground state of electronic configuration of chromium atom is
Answer:
The ground state electronic configuration of a chromium (Cr) atom is [Ar] 3d5 4s1. This configuration arises from the electron filling pattern where half-filled and fully-filled orbitals are more stable than partially-filled orbitals due to exchange energy and electrostatic repulsions. Chromium has 24 electrons, distributed across different orbitals. In the case of chromium, one electron is removed from the 4s orbital and is added to the 3d orbital to achieve a more stable configuration. This results in the 3d orbital being half-filled, which is a more stable configuration.
