10.3 Why are alkali metals not found in nature ?

Answers (1)

Electronic Configuration All the alkali metals have one valence electron, ns^{1}  outside the noble gas core. The loosely held s electron in the outermost valence shell of these elements makes them the most electropositive metals. They readily lose an electron to give monovalent M+ ions. Hence they are never found in the free or native state in nature.
