Question

1. atoms may emit light energy when ______. protons move to a higher energy level electrons move to a higher energy level electrons move to a lower energy level protons move to a lower energy level

Explanation:

When electrons move to a lower energy level, they release energy in the form of light (photon). Protons do not move between energy levels in this context. Electrons moving to a higher energy level absorb energy, not emit it.

Answer:

electrons move to a lower energy level
