Mar 31, 2015 · The basic premise of this method is that we remove all of the ligands from the metal and, if necessary, add the proper number of electrons to each ligand to bring it to a closed valence shell state. For example, if we remove ammonia from our metal complex, NH 3 has a completed octet and acts as a neutral molecule. 334. What elements possess four valence electrons? 336. Materials that might have eight valence electrons. C. Valence and inner electrons are the carriers in conductors.
