Question 46 • Chemistry

An electron in a hydrogen atom moves from level 1 to level 4. The electron then drops from level 4 to level 2. Which statement describes the most likely result?

Answer
A
The energy absorbed in the first move is greater than the energy released in the second move.
B
The energy absorbed in the first move equals the energy released in the second move.
C
The energy released in the first move equals the energy absorbed in the second move.
D
The energy released in the first move is greater than the energy absorbed in the second move.

Explanation

The move from level 1 to level 4 absorbs energy equal to the difference between those levels. In hydrogen, this is about 12.75 eV; the drop from level 4 to level 2 releases about 2.55 eV. Because level 2 is higher in energy than level 1, the first energy difference is larger, so the energy absorbed is greater than the energy released.
