  • Alkaline earth metal - Wikipedia

    en.wikipedia.org/wiki/Alkaline_earth_metal The alkaline earth metals are all silver-colored and soft, and have relatively low densities, melting points, and boiling points. In chemical terms, all of the alkaline earth metals react with the halogens to form the alkaline earth metal halides, all of which are ionic crystalline compounds (except for beryllium chloride, which is covalent).
