Question

Which best explains what happens when an electron moves from an excited state to the ground state?

The electron absorbs energy as it moves to a lower energy level.
The electron absorbs energy as it moves to a higher energy level.
The electron releases energy as it moves to a higher energy level.
The electron releases energy as it moves to a lower energy level.

Answer 1

The electron releases energy as it moves to a lower energy level.

Explanation: When an electron transitions from an excited (higher) energy level to the ground (lower) state, the energy difference is emitted—usually as a photon of energy ΔE = hν.
