For paramagnetic compounds in transition metals, the final electron of the outermost orbital—which last shell has how many electrons, or showed have d-d transitions or V.B.T in this there electron filling in the d orbital as in free state and combined state—is what is responsible for paramagnetic behavior.
If a molecule contains 10, 16, or odd numbers of electrons overall, it is said to be paramagnetic.
An atom having one or more unpaired electrons is said to be in a paramagnetized condition. The magnetic dipole moments of the electrons cause a magnetic field to draw in the unpaired electrons.
An odd electron system or a molecule with one or more unpaired electrons is paramagnetic. NO has 15 electrons, a 2. 5 bond order, 1 unpaired electron in antibonding orbitals, and 15 electrons in total. The molecule NO is hence paramagnetic.
