What are alkali metals? Learn the alkali metals definition, alkali metals properties, characteristics of alkali metals, and why alkali metals are so reactive. Related to this Question What are the properties of water? What are the properties of transition metals?
Alkali metals are the elements of group 1 of the periodic table that when reacts with water, produces an alkaline solution, along with the release of hydrogen gas. Alkali metals include lithium, sodium, potassium, rubidium, and cesium.
