Each time an electron moves from a higher energy level to a lower energy level
A) a photon is absorbed.
B) an electron is absorbed.
C) an observer will not see any light.
D) an electron disappears as some point between two levels.
E) a photon or some heat is given off.

Question

Quizplus · Accepted Answer

When an electron moves from a higher energy level to a lower energy level, it releases energy in the form of a photon or some heat. This process is known as the emission of radiation or emission spectra. The frequency and energy of the photon released are determined by the energy difference between the two levels that the electron transitions between. Therefore, choice E stating that "a photon or some heat is given off" is the best choice.
