WebFlame Test Lab Report. 1017 Words5 Pages. Introduction: In the flame test, the electrons of the flame become excited through the application of heat whilst at the same time reacting with the gas (emitted from the reaction of a metal carbonate and hydrochloric acid). This ‘excitement’ causes electrons to move from their current energy level ... WebFlame Test Lab Introduction/Purpose: When a certain amount of energy is supplied within an atom‚ the electrons of that atom begin to move up the levels of electron configuration. This level of energy is called a quantum. The object of this experiment was to examine the movement of electrons up and down energy levels through the use of given elemental …
