When an electron drops to a lower energy level in an atom,
A)the extra energy disappears.
B)the atom moves more slowly.
C)light at a wavelength specific to the change in energy levels is emitted.
D)the electron becomes more massive.

Question

Quizplus · Accepted Answer

When an electron drops to a lower energy level in an atom, the energy difference is released in the form of an electromagnetic wave (light) with a specific wavelength. This is known as atomic emission spectra and is used to identify elements. The other options (A, B, and D) are incorrect as they do not accurately describe what happens when an electron drops to a lower energy level.
