What are alkali metals? Why do these metals not occur in free state in nature? List the principal ores of alkali metals.
Alkali metals are: - Lithium (Li); - Sodium (Na); - Potassium (K); - Rubidium (Rb); - Cesium (Cs); - Francium (Fr). All alkali metals have their outmost electron in the s-orbital. This pre-determines their high chemical...
