Question

What causes the emission of light in atomic spectra? A. Electrons emitting energy and moving to lower energy levels. B. Neutrons emitting energy and moving to lower energy levels. c Protons absorbing energy and moving to higher energy levels. Electrons absorbing energy and moving to higher energy levels.

Answer 1

The correct answer is A. Electrons emitting energy and moving to lower energy levels.When an electron in an atom absorbs energy, it can move to a higher energy level. However, this excited state is unstable, and the electron will eventually fall back to a lower energy level. As it does so, it emits energy in the form of light. This light corresponds to specific wavelengths, which are seen as distinct lines in the atomic spectrum.
