The number of valence electrons in transition metals could very in different ceramics. Calculate the number of valence electrons of Nb in Nb oxides NbO, NbO2, and Nb2O5.
Homework Answers
Electronic configuration of Nb : [Kr] 4d4 5s1
Number of valence electrons = 5
1. In NbO : oxidation state of Nb = +2
Valence electrons = 5 - 2 = 3
2. In NbO2 : oxidation state of Nb = +4
Valence electrons = 5 - 4 = 1
3. In Nb2O4 : oxidation state of Nb = +4
Valence electrons = 5 - 4 = 1

O THE TRANSITION METALS Adding electrons to a crystal field theory energy level di. The energies of the valence d orbitals on the iron atom in the tetrahedral Fe(CN), complex are split according to the electron box level diagram below.

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. Part A...
