Simple ligands include water, ammonia and chloride ions. What all these have got in common is active lone pairs of electrons in the outer energy level. These are used to form co-ordinate bonds with the metal ion. All ligands are lone pair donors. WebP is also found here which is higher in energy. This means the two term symbol states are 4F and 4P. In the effect of the ligand field the term symbols split. The 4P and the 4F have orbital splitting energy of 15B, this is explained later on. So there are possible electron configurations in a strong ligand field case. easy diy patio couch
