Properties of Alkali MetalsAlkali metals are the elements found in Group 1 of the periodic table, including lithium, sodium, potassium, rubidium, cesium, and francium.These elements share distinctive physical properties. They're soft, silvery-white metals with low densities that increase down the group. They also have low melting and boiling points compared to other metals.Alkali metals are characterized by having just one electron in their outermost shell, making them highly reactive. This single valence electron is easily lost, forming positive ions with a +1 charge.Their reactivity increases dramatically as you move down the group, with cesium and francium being so reactive they can ignite spontaneously in air.
