http://api.3m.com/difference+between+valence+bond+theory+and+crystal+field+theory WebThe Crystal Field Theory (CFT) is a model for the bonding interaction between transition metals and ligands. It describes the effect of the attraction between the positive charge of the metal cation and negative charge on the non-bonding electrons of the ligand.

WebThis electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals. CFT focuses on the nonbonding electrons on the central metal ion in coordination complexes not on the metal-ligand bonds. 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. in wheel barrow which two mechanism is used
