1 Silver (Z = 47) can exhibit +2 oxidation state wherein it will have
incompletely filled d-orbitals (4d), hence a transition element 4 2 In the formation of metallic bonds, no eletrons from 3d-orbitals are involved
in case of zinc, while in all other metals of the 3d series, electrons from
the d-orbitals are always involved in the formation of metallic bonds 4
