Question

Determine the number of valence electrons in each of the following elements. NOTE: When electrons are added to the outermost d shell of a transition metal, sometimes the first electrons that go into the shell tend to act like normal valence electrons. This is not always the case, however. For the purpose of this problem, please count the outermost d electrons as among the valence electrons (even though they are not in an outermost d principal energy level.
