Using crystal field theory, draw an electron box energy level diagram for the valence d orbitals on the molybdenum atom in a tetrahedral [MoBr4] complex Your diagram should show the relative energy of each orbital, and the number of electrons in each orbital. Note: to make your diagram easier to read, label the d orbitals with just the subscript. For example, label the d2 orbital with just z². Energy 1 S |
