STEM Transition Elements Problem 18: Why are most compounds of transition metals in the first series colored and paramagnetic?
Because they possess completely filled 3d10 orbitals
Due to nuclear fission within the metal atom
Due to the presence of unpaired electrons in 3d orbitals that absorb specific wavelengths of visible light for d-d excitation
Because of the total absence of electrons in the d-subshell
