Oxidation Numbers In order to keep track of electron transfers in oxidation-reduction reactions, it is convenient to introduce the concept of oxidation numbers. Oxidation number rules: Elementshave an oxidation number of 0 Group Iand II– In addition to the elemental oxidation state of 0, Group I has an oxidation state of +1and Group II has an oxidation state of +2. Confirm this by assigning oxidation numbers to the manganese atoms. The number of electrons produced must equal the number of electrons consumed. Describe how ionic, covalent, and metallic bonds form and provide examples of substances that exhibit each type of bonding. Oxygen (O) and Sulfur (S) all have an electron configuration that ends as #s^2 p^4#. They can see the difference between the number of protons (+) and electrons (-), which relates to the charge or oxidation number. The most stable valence is one that fills or half … Valency is the number of electrons present in the outermost shell of a particular element whereas oxidation state is the number of electrons that an element in a particular compound has lost or gained. Oxidation Numbers Metals (Positive Ions) Positive because they LOSE electrons. Worksheet counting valence electrons fill in the table. Valence electrons are the electrons that occupy the outermost shells or orbitals of an atom. 8. O Na F N Ca Ar 3. Predict reactivity of metals and nonmetals from general periodic trends. (Representative groups including multiple oxidation states for tin and lead.) Na 2 O 2 Na O 2. SiO 2 Si O 3. 7.
