Energy is absorbed in this transition.
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). Moving from n = 2 to n = 6 means moving from a lower state to a higher state. Therefore, energy would be absorbed.
