Atomic spectra are due to the changes in the energy of ________
A)protons.
B)neutrons.
C)nuclei.
D)electrons.
E)electromagnetic radiation.

Question

Quizplus · Accepted Answer

Atomic spectra are a result of changes in the energy of the electrons in an atom. When an electron changes energy levels, it emits or absorbs energy in the form of electromagnetic radiation, which produces the characteristic spectral lines observed in atomic spectra. Protons, neutrons, and nuclei do not play a direct role in producing atomic spectra.
