-Drawing a crystal field theory energy level diagram Using crystal field theory, draw an electron box energy level diagram for the valence d orbitals on the vanadium atom in a 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 d.2 orbital with just z energy
