What is oxidation state?
The term "oxidation state" in chemistry refers to the charge that an atom would have if all of its interactions to other atoms were fully ionic (also known as "oxidation number"). It describes how much an atom has been oxidized in a chemical molecule. Zero, positive, and negative oxidation states are all possible.
Why is electron loss called oxidation?
The word "oxidation" was created by Antoine Lavoisier to describe a substance's reaction with oxygen. The phrase was eventually expanded to include additional reactions in which electrons are lost, whether or not oxygen was present, after it was realized that the substance loses electrons when it is oxidized.
