Reactive substances have a high level of reactivity and easily participate in chemical reactions, often leading to the formation of new compounds. For example, alkali metals like sodium and potassium are highly reactive and react vigorously with water.

Reactive materials exhibit a significant response or change in their properties when subjected to specific conditions, such as temperature, pressure, or light. Examples include thermochromic pigments that change color with temperature or piezoelectric materials that generate an electric charge when mechanically stressed.

These systems are often used in areas like artificial intelligence, robotics, and data analytics.

    5. (General) More broadly, reactive can describe anyone or anything that responds or reacts to a given situation, problem, or external factor. It typically implies a response that is instinctive, automatic, or spontaneous, rather than planned or proactive.
