The Group 1 metals are all highly reactive silvery metals that are so reactive to air and moisture that they must be stored under an inert atmosphere or oil. The name “ alkaline ” comes from the fact that compounds of these elements form basic (pH greater than 7) or alkaline solutions when dissolved in water. The only element in the first column that is not usually considered an alkali metal is hydrogen.Hydrogen and the alkali metals make up the group 1 elements of the periodic table. Created: Jul 20, 2010 | Updated: Sep 25, 2012. Because of the high affinity of alkali metals to halogens, they are important in organic and inorganic syntheses which produce alkali metal halides as the result of condensation and metathesis reactions. Elements of the group have one s-electron in the outer electron shell. The energy needed to remove the most loosely attached 1 mole electron of an isolated gaseous 1 mole atom to form one mole cation. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior. They have just one electron in their outer shell, and they are ready to lose it in ionic bonding with other elements. This battery is used in many electronics and can be recharged. The metals consist of the alkali metals, alkaline earths, transition metals, lanthanides, and actinides. In 1832 he obtained his Ph.D. If so, you will need to have a type D fire extinguisher. Davy discovered sodium while passing an electric current through sodium hydroxide. Alkali metals dissolve readily in liquid ammonia and dilute solutions are blue but concentrated ones show a bronze color. Rubidium reacts quickly with O2 and is useful in vacuum tubes and photocells.
