Vedclass · Answer

(A) Alkaline earth metals have high ionization enthalpy. When heated in a Bunsen flame,the energy of the flame is not sufficient to excite the electrons to higher energy levels in the case of $Be$ and $Mg$. Therefore,$Be$ and $Mg$ do not impart any characteristic colour to the flame. Other alkaline earth metals like $Ca$,$Sr$,and $Ba$ impart characteristic colours to the flame due to the excitation of electrons.

The alkaline earth metals,which do not impart any colour to Bunsen flame are
