\\Cr = 3d^54s^1\\ Cu = 3d^{10}4s^9

 In the second transition series different electron configuration shown by following metals, 

Mo(42) = 4d5 5s1, Tc(43) = 4d6 5s1, Ru(44) = 4d7 5s1, Rh(45) = 4d8 5s1, Pd(46) = 4d10 5s0, Ag(47) = 4d10 5s1

In 3rd series there are also some metals which show this types of behaviour such as;
