52. FINAL ROUND Question
Glow in the dark objects glow in the dark, but not when light is shining on them. The “glow” in the dark is due to the process of phosphorescence. Explain this process based on what you learned about electrons in chapter 5.
ANSWER
BACK TO GAME

53. FINAL ROUND Answer
Glow in the dark objects glow in the dark, but not when light is shining on them. The “glow” in the dark is due to the process of phosphorescence. Explain this process based on what you learned about electrons in chapter 5.
As long as the lights are on the atoms in the stars are absorbing energy, and the electrons in the atoms remain in their highest energy level. Once the lights are turned off, the atoms are no longer absorbing energy and the electrons can drop to the ground state, emitting light in the process.
