These elements are highly reactive and are rarely found in nature in their elemental form.
These elements are highly reactive and are rarely found in nature in their elemental form. Removing one electron gives them a stable noble gas electron configuration, and hence they frequently bond with halogens in a 1 to 1 ratio to form basic salts. Hydrogen, despite being in the same periodic group as these elements, is typically not included because of its very high ionization energy. For ten points, give this name for Group 1 of the periodic table, including rubidium, potassium and sodium.
