Answer

Energy would be emitted when the hydrogen electron moves from n = 4 to n = 2.

Work Step by Step

Just remember that: - Energy must be absorbed to move an electron from a lower state (lower energy) to a higher state (higher energy). - Energy would be emitted as an electron moves from a higher state (higher energy) to a lower state (lower energy). Going from n = 4 to n = 2 means moving from a higher state to a lower state. Therefore, energy would be emitted.
