Vedclass · Answer

(C) The flame test is based on the excitation of electrons to higher energy levels by the heat of the flame,which then emit light upon returning to the ground state. $Be$ and $Mg$ atoms are small and have high ionization enthalpies,so the energy provided by the Bunsen flame is not sufficient to excite their electrons to higher energy levels. Therefore,$MgCl_2$ does not impart any characteristic color to the flame.
