The fact that the absorption and emission spectra of atoms and their ions are different is evidence that the spectra are due to ________
A)electrons.
B)protons.
C)neutrons.
D)the nuclei.
E)electromagnetic interactions.

Question

Quizplus · Accepted Answer

The absorption and emission spectra of atoms and their ions are due to the behavior of electrons. When electrons absorb energy, they move to higher energy levels and emit energy when they move back down to lower energy levels. The energy levels in an atom are quantized, causing the electron transitions to be discrete and resulting in the unique spectra of each element. The absorption and emission spectra of atoms and their ions differ due to different electron configurations and energy levels in these species.
