WebThe crystal field with D 2d symmetry splits the ground state (2 F 5/2) and excited states (2 F 7/2) into three and four doublets, respectively. Only the lowest doublet is populated; therefore, the Ce 3+ ion has an effective spin S = ½, as mentioned earlier. Webcrystal system with the lowest symmetry. lowest. thermodynamics suggest that atoms strive toward the _____ possible energy state. 2-O has a valence of. 1-F and Cl have a valence of. 1+ Na and K have a valence of. 2+ Mg, Ca, Mn, and Fe have a valence of. 3+ Al, Cr, and Fe have a valence of. 4+
