Alkali metals are shiny, soft, highly reactive metals in group 1 of the periodic table. They have similar chemical properties and form cations with charge +1. Learn about their occurrence, history, biological role and uses in atomic clocks, lamps and batteries.
17 wrz 2024 · Alkali metal, any of the six elements of Group 1 (Ia) of the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).
