When an excited electron in an atom moves to the ground state, the electron:

1. absorbs energy as it moves to a higher energy state
2. absorbs energy as it moves to a lower energy state
3. emits energy as it moves to a higher energy state
4. emits energy as it moves to a lower energy state

Answer is: (4) emits energy as it moves to a lower energy state.
Atom emits a characteristic set of discrete wavelengths, according to its electronic energy levels.
Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state.
Each transition has a specific energy difference.
Each element's emission spectrum is unique.

When an excited electron moves to its ground state, it emits energy in the form of a photon. This process involves the electron transitioning from a higher energy level to a lower one, releasing the energy difference as light. Therefore, the correct answer is option 4: emits energy as it moves to a lower energy state.
