The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive. Because alkali metals are so reactive, they are found in nature only in combination with other elements.
The alkali metals are lithium, sodium, potassium, rubidium, cesium, and francium.Alkali Metal Properties. The alkali metals exhibit many of the physical properties common to metals, although their densities are lower than those of other metals.Alkali metals have one electron in their outer shell, which is loosely bound.This gives them the largest atomic radii of the elements in their respective periods.he alkali metals are lithium, sodium, potassium, rubidium, cesium, and francium.
