chemical elements

Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: Lithium , Sodium , Potassium , Rubidium, Cesium , and Francium . Hydrogen, though listed in Group 1 due to its electronic configuration, is not included in the alkali metals since it rarely exhibits similar behavior. The word "alkali" received its name from the Arabic word "al qali," meaning "from ashes". These particular elements were given the name "alkali" because they react with water to form hydroxide ions, creating basic solutions , which are also called alkaline solutions.
