The correct electronic configuration for 24Cr (Chromium) is:
1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s¹
This configuration shows that Chromium has a half-filled d subshell (3d⁵), which is a stable configuration. Note that Chromium is an exception to the Aufbau principle, as it would be expected to have a 4s² configuration, but the half-filled d subshell is more stable.

The atomic number of chromium (Cr) is 24. To determine its correct electron configuration, we can use the Aufbau principle, which states that electrons fill the lowest energy orbitals first. The electron configuration for chromium (Cr) is as follows:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d⁵
So, the correct electronic configuration for chromium (Cr) is:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d⁵.
