2019-1-24 · The jumps that you can see in flame tests often come from electrons falling from a higher to a lower level in the metal atoms. So if, for example, you put sodium chloride, which contains sodium ions, into a flame, where do the atoms come from? In the hot flame, some of the sodium ions regain their electrons to form neutral sodium atoms again.

2013-5-15 · Such crude analyses are known as flame tests. Only metals, with their loosely held electrons, are excited in the flame of a laboratory burner. Thus, flame tests are useful in the identification of metallic ions. Many metallic ions exhibit characteristic colors when vaporized in the burner flame.

2008-6-22 · Part One: Flame Tests (As an option, this could be a demo rather than a student activity) When solutions of metals are heated in a Bunsen burner flame, they give off characteristic colours. For example, sodium makes the flame turn bright yellow – this is the same yellow colour made by sodium street lamps and many fireworks.
