Which of the following series of transition elements has general electronic configuration, [Kr] ?

(A)3d series elements
(B)4d series elementsCorrect
(C)5d series elements
(D)6d series elements

Answer: (B)

Solution

The core [Kr] ends at (Z = 36). Filling of the 4d subshell, with 5s partly filled, gives the second transition series (4d series) from yttrium (Z = 39, ) to cadmium (Z =
