Energy is emitted in this case.

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). We see that the radius of orbit in this case has decreased, or the atom contracts. This is a sign that the hydrogen electron has jumped from a higher state to a lower state, since a lower state would be nearer to the nucleus than a higher state. Overall, energy would be emitted.
