Reactivity refers to the tendency of a substance to undergo chemical reactions, often characterized by its ability to interact with other substances and change its chemical composition.
Highly reactive substances readily participate in reactions, while less reactive ones may require specific conditions or catalysts to engage in chemical transformations.
Reactivity is a crucial concept in chemistry, influencing the behavior of elements and compounds in various contexts, from industrial processes to biological reactions. Understanding reactivity is essential for predicting and controlling chemical changes.
