alkali metals are monovalent explain?

Expert Answer
Dear Student
Alkali metals have the lowest first ionization energy in each period. They can easily lose the valence electron and form monovalent cations.
The removal of the electron from alkali metals causes the formation of monovalent cations having very stable electronic configurations (same as that of noble gases).
The second ionization energy is very high. Therefore, it becomes very difficult to remove the second electron from the stable noble gas configurations.
We hope that clarifies your query.
