AI overview

Redox reactions occur when one atom gives electrons to another atom—the atom losing electrons is oxidized while the atom gaining electrons is reduced. These reactions are important because they power everything from chemical bonding to dramatic reactions like combustion and can release large amounts of energy.

Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. The oxidation and reduction processes occur simultaneously in the chemical reaction.
