Cobalt iii oxide formula series#

As 3d and 4s are close in energy, it has maximum number of e -1 s to loose or share. This is because its outer EC is 3d 54s 2.

Cobalt iii oxide formula series#

Which of the 3d series of the transition metals exhibits the largest number of oxidation states and why?Īns: Manganese (Z = 25) shows maximum number of O.S. This means that the metallic bonds are quite weak in zinc and it has therefore, lowest enthalpy of atomisation in the 3d series.Ĩ.3. However, in all other elements belonging to 3d series one or more d-electrons are involved in the metallic bonds. In case of zinc (3d 104s 2 configuration), no electrons from the 3d-orbitals are involved in the formation of metallic bonds since all the orbitals are filled. Why?Īns: The enthalpy of atomisation is directly linked with the stability of the crystal lattice and also the strength of the metallic bond. In the series Sc(Z = 21) to (Z = 30), the enthalpy of atomisation of zinc is the lowest i.e., 126 kJ mol -1. And in + 2 O.S., the electronic configuration is d 9 i.e, d-subshell is incompletely filled. How can you say that it is a transition element?Īns: The outer electronic configuration of Ag (Z=47) is 4d 105s 1. Silver atom has completely filled d orbitals (4d 10) in its ground state.
