how many unpaired electrons are present in chromium
How many unpaired electrons are present in chromium?
Answer:
In the case of chromium, the electron configuration is [Ar] 3d^5 4s^1. Chromium has a total of 24 electrons. When filling the electron orbitals, the 4s orbital is filled before the 3d orbitals, which leads to an exception in the configuration. Chromium has 6 unpaired electrons, considering the 5 unpaired electrons in the 3d orbitals. This configuration makes chromium exhibit interesting magnetic properties.
