This page explains what oxidation states (oxidation numbers ) are and how to calculate and use them. Oxidation number is defined as the total number of electrons that an atom either gains or loses to form a chemical bond with another atom. Let's learn about oxidation number in detail, including its rules and steps to calculate it with the help of examples. The oxidation state or oxidation number is an atom's charge after ionic approximation of its bonds. How to calculate oxidation state Read our article on finding oxidation states for a compound or use our oxidation numbers calculator to do it for you. You can also ask for help determining oxidation numbers in our chat or forums. In chemistry, the terms " oxidation " and "reduction" refer to reactions in which an atom (or group of atoms) loses or gains electrons, respectively.
