Some of the examples of these occurrences would be table salt, you may not realize this but sodium makes up almost all of the little grains. Any alkali metal, on coming in contact with air or oxygen, starts burning and oxides are formed in the process. Potassium hydroxide is used to make detergents. Alkali metals are elements that are not found in nature in a free state, but rather in the form of ionic compounds because these metals easily lose their valence electron and they are the most powerful reducing agents, Preparing of these metals involves the electrolysis of their molten (fused) halides. Uses of alkali metals: i. Lithium metal is used to make useful alloys. Therefore, they are ready to lose that one electron in ionic bonding with other elements. Alloy of Lithium is used in aircraft building. It has relatively few commercial uses and pure metal is combined with other metals to form alloys.
