When an electron in an atom goes from a higher energy state to a lower energy state,the atom
A)emits a photon of a specific frequency.
B)absorbs a photon of a specific frequency.
C)absorbs several photons of a specific frequency.
D)can emit a photon of any frequency.
E)can absorb a photon of any frequency.

Question

Quizplus · Accepted Answer

When an electron in an atom goes from a higher energy state to a lower energy state, it releases energy in the form of a photon with a specific frequency. This is known as emission. Therefore, the correct answer is A. B, C, D, and E are incorrect as they refer to photon absorption, multiple photon absorption, and arbitrary photon emission or absorption, which are not the typical results of an electron moving to a lower energy state.
