Oxidation state: Learn what oxidation state is

Learn what oxidation state is, how to calculate it, and why it is important for chemical reactions. Find out the lowest and highest oxidation states, the rules for assigning oxidation numbers, and examples of oxidation state calculation. Gives the degree of oxidation of an atom in terms of counting electrons. The higher the oxidation state (OS) of a given atom, the greater is its degree of oxidation . Definition: OS of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds. Learn what oxidation state is, how to calculate it, and how it relates to redox reactions. Find out the general rules, solved examples, and trends in oxidation states of different elements and compounds. Learn how to calculate the oxidation state of an atom based on its valence electrons. Find the most common oxidation states of all 118 elements in a table with bold and italic values.
