Write the ground state electron configurations for the following atom. Chromium (Cr) Determine the total number of unpaired electrons. Determine the magnetic properties (paramagnetic or diamagnetic).
6 unpaired electrons
Paramagnetic are those which has unpaired electrons and diamagnetic are those in which all electrons are paired.
Given, Chromium (Cr) the atomic number – 24
The electronic configuration is –
There are 5 unpaired electrons in 3d and 1 unpaired in 4s. Total number of unpaired electrons = 6
Thus, the element is paramagnetic as the electrons are unpaired.
