electrons moving from one energy level to another emit photons. always true sometimes true never true
electrons moving from one energy level to another emit photons. always true sometimes true never true
Answer
Brief Explanations:
When electrons move from a higher - energy level to a lower - energy level, they emit photons (according to the Bohr model of the atom). However, when electrons move from a lower - energy level to a higher - energy level, they absorb photons. So, electrons do not always emit photons when moving between energy levels.
Answer:
Sometimes True
