The oxidation number of lithium in lithium nitrate is 1. Formula: LiNO3. Hill system formula: Li1N1O3. CAS registry number: [7790-69-4] Formula weight: 68.946. Class: nitrate. Colour: white. Appearance: crystalline solid.
The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element. Thus, the atoms in O2, O3, P4, S8, and aluminum metal all have an oxidation number of 0. 2. The oxidation number of simple ions is equal to the charge on the ion. The oxidation number of sodium in the Na+ ion is +1, for example, and the oxidation number of chlorine in the Cl- ion is -1. 3. The oxidation number of hydrogen is +1 when it is combined with a nonmetal as in CH4, NH3, H2O, and HCl.
