CoorCoordinationdination Alfred Werner (1866-1919), a Swiss chemist was the first to formulate his ideas about the structures of coordination compounds. This oxidation number is an indicator of the degree of oxidation (loss of electrons) of an atom in a chemical compound. tetrahedral, linear 2. Proceed to remove all atoms around carbon assigning oxidation states to H … (where, Z = atomic number of metal atom ON = oxidation number of metal and CN = coordination number of complex) An ion with central metal atom having EAN equal to next inert gas will be more stable. The oxidation number is basically the count of electrons that atoms in a molecule can share, lose or gain while forming chemical bonds with other atoms of a different element.
