Question

Alkali metals do not form divalent ions why

Answer 1

alkali metals have one electron in their outmost shell therefore after loosing it they form monovalent ions removal of one more electron requires a very high amount of energy so the removal of second electron is difficult and that os why don't form divalent ions.

Answer 2

Alkali metals have one electron in their outermost shell therefore after loosing it they form monovalent ions removal of one more electron requires a very high amount of energy so the removal of second electron is difficult and thatis why don't form divalent ions.
