Information on Alkali Metals

In their pure forms, the alkali metals (lithium, sodium, potassium, rubidium, and cesium) are soft, shiny metals with low melting points. Alkali metals react readily with air and moisture. Due to their reactivity, special precautions must be taken when using and storing these metals. Lithium, sodium, potassium, rubidium, and cesium (L-R). Get price
