The highest oxidation state for each of the elements from Sc to Zn has to be determined. Concept Introduction: Oxidation number : It is the charge of the atom in a molecule if electrons were completely transferred. The oxidation state of free element is zero. Transition metals shows variable oxidation states in their compounds. Oxidation: If electrons are moved from a species during a chemical reaction . The species whose electrons are removed is said to be oxidized. Oxidizing agent: The substances that are capable to oxidize other species by accepting electrons from those species are called oxidizing agent which gets reduced during the process. Effective nuclear charge: It is the charge experienced by the valence electrons from the nucleus. Effective nuclear charge increases across a period because increasing nuclear charge with no accompanying increase in shielding effect.
