The alkali metals are found in group 1 of the Periodic table. They are very reactive metals and do not occur freely in nature. Alkali metals are malleable‚ ductile‚ and are good conductors of heat and electricity. Alkali metals can also explode if they are exposed to water. The Alkali metals are: lithium‚ sodium‚ potassium‚ rubidium‚ cesium‚ and francium. Lithium The mineral petalite‚ which contains lithium‚ was discovered by a Brazilian scientist named Jose Bonifacio towards the end of the
