They all consist of chlorine and most are alkaline metals besides hydrogen, which is a nonmetal. The properties of these metals have low boiling points, have low densities, produce hydrogen gas when reacting with water, and dissolve in water to form alkaline solutions. On the other hand, hydrogen is a nonmetal, is nontoxic, and is a diatomic gas. Chlorine, which is the most abundant in this case, is a halogen and combines with almost all other elements. It was discovered by Carl Wilhelm Scheele in 1774 but was named by Humphry Davy. Besides being in the compounds of stomach acids, it can also be found in water purification, disinfectants, bleach, medicine, and mustard gas. Furthermore, when looking at the periodic table trends, pH is more basic as you go from left to right, which is also the same for the electronegativity trend. This means that your alkali metals are more acidic than the noble
