Interpretation: It should be determined that where in the periodic table are the most easily reduced and oxidized elements found.
Concept introduction:
Oxidation: Losing electrons, increasing oxidation number.
Reduction: Gaining electron, decreasing oxidation number.
Oxidizing agent is a substance that removes electrons from another reactant in a
Reducing agent is the element or compound in a
The number of electrons an atom tends to give up or gain in a chemical reaction is called oxidation number.
