What are alkaline metals?
The alkali metals are the elements found in the first group of the periodic table. They are Lithium (Li), sodium(Na), potasium (K), Rubidium (Rb), Cesium (Cs) and Francium (Fr). They are all metals and very reactive and none of these metals do not occur as free metals in nature. Alkali metals are always stored in inert liquids such as kerosen because they rapidly react with the air, water vapour and oxygen in the air. Sometimes they explosively react with other substances. They can achieve the noble gas state easily, by removing the outermost electron in the valence shell.
The densities of Lithium and Sodium are less than the density of water. However, the other elements are denser than water. Many of alkali metal compounds (NaCl, KCl, Na2, CO3, NaOH) are commercially very important
