"WebThe alkali metals react readily with atmospheric oxygen and water vapour. (Lithium also reacts with nitrogen .) They react vigorously, and often violently, with water to release hydrogen and form strong caustic solutions. Most common nonmetallic substances such as halogens, halogen acids, sulfur, and phosphorus react with the alkali metals. " - Reactivity trend of alkali metals

Reactivity trend of alkali metals

WebThe alkali metals all react violently with water according to M + H 2 O → MOH + 1/2 H 2. The rate of the reaction depends on the degree of metal surface presented to the liquid.
