RANK the electron transitions below based on how much energy is released during the transition. (1-least energy, 5-most energy) Drag the numbers to the RANK column.
Then, based on how you ranked the energy, match each transition to a color of light that would be released. Drag the colors to the COLOR column.
You can use the electromagnetic spectrum that is projected on the front board to recall which colors have more or less energy.
