What is Reactivity?
Reactivity in chemistry refers to the tendency of a substance to undergo chemical reaction, either by itself or with other materials, and to release energy during that reaction. Reactivity is determined by electronic structure, molecular geometry, and thermodynamic and kinetic factors. The reactivity series (activity series) ranks metals by their tendency to undergo oxidation reactions.

High reactivity = potential hazard. Highly reactive materials: alkali metals (H₂ generation with water), strong oxidizers (peroxides, permanganates), reactive gases (F₂, Cl₂). Incompatible chemical storage — reactive pairs must be separated. Reactivity hazard classes on GHS labels.
