Definition
活性 means 'chemically or biologically active' and is typically used as an attributive adjective in technical contexts, such as to describe the state of a substance that can react or produce an effect. It appears in compounds like 活性炭 (activated charcoal) and 活性成分 (active ingredient). Unlike general words for 'active' (活跃, 积极), 活性 is specifically scientific and not used for people or everyday enthusiasm.
