Alkaline earth metal - Wikipedia

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 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 ).

Transition Metals - 4College.co.uk

Transition metals are all dense metals with high melting and boiling points. They are often hard and durable, with high tensile strength and good mechanical properties. These properties are the result of metallic bonding between the atoms in the metal lattice.
