In the flame test lab, metal ions are heated on wooden splint in the form of a liquid that were previously soaked in a solution of metals. These electrons get heated at the same temperature, however the energy that is needed to excite each electron in the different metals is not the same. This means that the energy levels that change are now unstable and need to cool down, and as soon as they are moved into the heat source through kinetic energy, a photon of light energy is created and this excites all electrons. The flames change colors based on the amount of excited electrons and this makes the colors range across a vivid spectrum from red, green, blue, yellow, and many more. These metals all proved that they have a different reactivity rate
