Alkali Metals

Alkali metals are a group of elements found in Group 1 of the periodic table, including lithium, sodium, potassium, rubidium, cesium, and francium. They are known for being highly reactive, especially with water, producing hydrogen gas and forming strong alkaline solutions. These metals are soft, shiny, and have low melting points. They typically exist in nature as compounds rather than pure metals, due to their reactivity. Alkali metals also play essential roles in biology and are used in various applications, such as batteries (lithium) and fertilizers (potassium). Their reactivity increases down the group.
