What is OXIDATION AND REDUCTION⚪

Oxidation and reduction are chemical processes that usually occur together and are called redox reactions. Oxidation: Loss of electrons by an atom, ion, or molecule. Reduction: Gain of electrons by an atom, ion, or molecule. For example: Na → Na⁺ + e⁻ Sodium loses one electron, so sodium is oxidized. Cl + e⁻ → Cl⁻ Chlorine gains one electron, so chlorine is reduced.
