Answer

Energy is absorbed 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 has increased, or in other words, the hydrogen atom expands in this case. The expansion of the hydrogen atom is a sign that the electron has moved to a higher state, since the higher the state, the further from the nucleus the electron is. Therefore, energy has been absorbed.
