Predicted Number of d-d Bands: - Cr(VI): No d-d bands as there are no d-electrons. - Mn(II): One d-d band as there is one possible transition (t2g to eg). - Co(II): Two d-d bands as there are two possible transitions (t2g to eg). - Ni(II): Two d-d bands as there are two possible transitions (t2g to eg). - Cu(II): One d-d band as there is one possible transition (t2g to eg)
