This worksheet is intended to be used as an introduction to the subject to show the rationale behind the rules for assigning oxidation numbers which you will need to learn. For Group I elements (the The key difference between valency and oxidation number is that valency is the maximum number of electrons an atom can lose, gain or share to become stable whereas oxidation number is the number of electrons an atom can lose or gain to form a bond with another atom. The maximum oxidation state of any transition element can generally be inferred from its total number of valence electrons. Remember that if the oxidation # increases it means oxidation and when it decreases it. WebThe number of electrons in each elements electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. The oxidation number of O in compounds is usually -2, but it is -1 in peroxides. They can consist of only one chemical element or compound with a single positive or negative charge.
