Alkali metals and alkaline earth metals are themselves very strong reducing agents ( high reduction potential values ) . While most metals form arsenides, only the alkali and alkaline earth metals form mostly ionic arsenides. Report an issue . Because of their high reactivity, the alkaline earths are not found free in nature. They all occur in nature, but are only found in compounds and minerals, not in their elemental forms. The alkaline earth metals are shiny, silvery-white, and somewhat reactive metals at standard temperature and pressure. The oxides of the alkaline-earth metals are basic (i.e., alkaline, in contrast to acidic). Elements in column 2 (the alkaline earth metals) always lose their valence electrons to form +2 ions. They are bitter in taste, slippery, and react with acids to make them neutralized. ALKALI METALS Found in group 1 of the periodic table (formerly known as group IA), Also called as active elements. Source(s): periodic table. They rarely occur in their pure form, however, because they are very reactive. The emission of this electron is easy, thus alkali metals are very reactive. Then, answer the questions that follow. The sulfate, RaSO4, is the most insoluble sulfate known, and the hydroxide, Ra(OH)2, is the most soluble of the alkaline-earth hydroxides.
