Reaktivní

Reaktivní is a term that can be used in several contexts, most commonly in chemistry and psychology. In chemistry, a reactive substance is one that readily undergoes chemical reactions. This means it has a strong tendency to combine with other substances or to decompose. Reactivity is influenced by factors such as the stability of the substance's chemical bonds, its electron configuration, and the presence of other molecules or conditions like temperature and pressure. For example, alkali metals are highly reactive and will readily react with water.

In psychology, the term "reactive" describes behavior or a response that is triggered by an external stimulus or event. A reactive person or system tends to react to changes rather than initiating them. This can manifest in various ways. For instance, a reactive coping mechanism might involve responding to stress only after it has occurred, rather than proactively managing potential stressors. Similarly, in user interface design, a reactive element is one that changes its appearance or behavior based on user interaction or other dynamic changes in the system. The opposite of reactive is often considered proactive, which implies taking initiative and anticipating future events. Understanding whether a situation or behavior is reactive or proactive can be important for problem-solving and strategic planning.
