A splitting of energy levels ("crystal field splitting") occurs because the orientation of the d orbital wavefunctions will increase an electron's energy when the orbital is located in a region of high electron density, and lower it when the reverse is true. In many-electron atoms the energy of an orbital depends on both n and l. C) Inner electrons shield outer electrons more effectively than do electrons in the same orbital. D) The splitting of sublevels in many-electron atoms is explained in terms of the penetration effect. E) The energy of a given orbital increases as the nuclear charge Z increases.

This is the bonding molecular orbital - and is of lower energy than the two 1s atomic orbitals of hydrogen atoms making this orbital more stable than two seperated atomic hydrogen orbitals. The upper molecular orbital has a node in the electronic wave function and the electron density is low between the two positively charged nuclei. 4. For the d9 case, using the "hole" formalism, the free ion term is 2D (one electron in the d orbitals); the strong field states are based on the trigonal bipyramidal (D3h) "d" orbital splitting and the location of the "hole". Because this is a one "hole" situation, each strong-field configuration only has one electronic state. 2A 1' dxz, dyz ...
