    The higher oxidation state of 4d and 5d series elements are generally more stable than those of the elements of 3d series, e.g., Mo, Tc (4d series elements) and W, Re (5d-series elements) form the oxyanions: MoVIO42− , TcVIIO42−, WVIO42−, ReVIIO4− which are stable and in which the transition elements concerned show their maximum oxidation states. The corresponding oxyanions of Cr and Mn namely CrVIO42− and MnVIIO4− are strong oxidising agents.
