Silver atom has completely filled d orbitals (4d 10 ) in its ground state. How can you say that it is a transition element? Ans: The outer electronic configuration of Ag (Z=47) is 4d 10 5s 1 . It shows+1 and + 2 O.S. (in AgO and AgF 2 ). And in + 2 O.S., the electronic configuration is d 9 i.e, d-subshell is incompletely filled. Hence, it is a transition element. 8.2. In the series Sc(Z = 21) to (Z = 30), t...
