Charge number oxidation number of a monatomic ion. For example, the oxidation number of <chem>Li+</chem> is +1. This helps when trying to solve oxidation questions. A charge number also can help when drawing Lewis dot structures. For example, if the structure is an ion, the charge will be included outside of the Lewis dot structure. Since there is a negative charge on the outside of the Lewis dot structure, one electron needs to be added to the structure. If the charge was positive, an electron would be lost and taken away. For an atomic nucleus, which can be regarded as an ion
