Why alkali metals do not form M2+ ions?
It is because after the loss of one electron, alkali metal ion (M+ ) is formed which has stable noble gas configuration and it is very difficult to remove another electron to form M2+ ion as the second ionisation enthalpy is very high. For example, when lithium loses one electron and forms Li+ which is similar to Helium atom.
