WebThe most basic crystal field argument includes point-symmetric charges approaching the central metal in a way as the ligands would. Then, any orbitals that are symmetry-equivalent will end up at the same energy, … WebJan 22, 2001 · Three groupings are considered in the following paragraphs. 1. I- < Br- < Cl- < F-. The crystal field model looks at electrostatic repulsions between the ligands and electrons in d-orbitals on the metal ion. The smaller the ligand, the closer it comes to the metal ion and thus the greater the repulsion. 2.
