Chromium energy level diagrams

Part (d) asks for an energy level diagram for this process. The electron starts in the ground state. On absorption of a photon, the electron moves to an energy level that is higher by 239 kJ/mol. The chromium ion loses 28.0% of its excited-state energy as heat as the electron moves to a different level...

Figure 8.21 An energy level diagram for dibenzenechromium. The positions of ring and chromium orbitals on this diagram are only approximate.

While the energy level diagrams and the corresponding spectroscopic transitions are relatively straightforward for light elements, they become very complex for heavier elements. The number of observed Hnes listed by Harvey [3] increases from the alkah metals with 30 (for lithium) to 645 (for caesium) to several thousand lines for the transition elements (chromium 2277, iron 4757, and cerium 5755 lines, respectively). 

The approximate energy level diagrams of ferrocene and dibenzene chromium are given in Figs. 3-11 and 3-12. 

The schematic diagram in Figure 2.12(a) shows the order in which the levels fill, from bottom to top in energy. For example, Ti has two 4s electrons, one in each spin level, and two 3d electrons, both with the same spin. Fe has two 4s electrons, one in each spin level, five 3d electrons with spin- , and one 3d electron with spin -i- . For vanadium, the first two electrons enter the 4, -j and 4s, +j levels the next three are all in the 3d, level, and vanadium has the configuration 4s 3d. The 3d, -j line crosses the 4s, +j line between V and Cr. When the six electrons of chromium are filled in from the lowest level,...
