Rules for assigning oxidation states
the oxidation state of an element is always zero the sum of the oxidation states of the elements in a
Oxidation and reduction reactions
Reactions in which both oxidation and reduction occur are called redox reactions. The acronym OILRIG might be familiar, reminding us
