How does flame test work

WebA flame test is a qualitative analysis used by the chemist to identify the metal and metalloid ion in the sample. Not all metal ions emit colour when heated in the gas burner. A flame … WebAs the metal ions are heated by the burner flame, some of their electrons absorb energy and move to excited states. As the electrons return to a lower energy, they emit light of a characteristic frequency corresponding to the amount of energy that they lost moving to the lower energy level.
