Five alkaline earth metals
WebThe alkaline earth metals have two valence electrons in their highest-energy orbitals (ns 2). They are smaller than the alkali metals of the same period, and therefore have higher ionization energies. In most cases, the alkaline earth metals are ionized to form a 2+ charge. The alkaline earth metals have much higher melting points than the ... WebNov 25, 2024 · 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. Their low ionization energies result in ...
