SUMMARY
The discussion centers on the electron configuration of cobalt, specifically its 3d7 configuration, which results in three unpaired electrons. Participants assert that cobalt is paramagnetic due to its odd number of unpaired electrons. The Aufbau principle is referenced to explain the filling of d orbitals, confirming that cobalt has two fully filled d electron pairs and three half-filled ones. The conclusion reached is that cobalt has three unpaired electrons, making it paramagnetic.
