Low ionization potential

Vedclass · Answer

(A) The alkali metals $(Group \ IA)$ exhibit a characteristic flame color because they possess low ionization potential. When heated in a Bunsen burner,the valence electrons absorb energy and are excited from a lower energy level to a higher energy level. As these excited electrons return to their ground state,they emit the absorbed energy in the form of visible light,which corresponds to a specific color.
