Step-by-step solution
Most transition metals have incomplete d-orbitals, which lead to unpaired electrons (paramagnetic behavior), variable oxidation states due to similar energies of ns and (n-1)d orbitals, and colored ions from d-d electronic transitions. Diamagnetic behavior (all electrons paired) is not typical for most transition metals, as their ions often contain unpaired electrons.
