INDEX NEXT UP PREVIOUS ATG What are the Alkali Metals? What are the Alkali Metals?

The Alkali Metals are the first family of the Periodic Table. They have one electron in their outer orbitals. In a chemical reaction, this outer electron is lost to form an ion with a single positive charge. The term alkali means basic with pH greater than 7 as opposed to acids which are less than 7. When these Metals combine with Non-Metals, the result is a base. Alkali Metals are silver-white, malleable, soft, and soluble in water. An Alkali Metal isolated in nature is rare because it reacts so readily with many Non-Metals especially the Halogens. [LM] {CI}
