Question

question 8 (mandatory) (1 point) atomic spectra are due to changes in the energy of a) nuclei. b) protons. c) neutrons. d) electromagnetic radiation. e) electrons.

Explanation:

Atomic spectra result from electrons transitioning between energy levels. When electrons move from a higher - energy level to a lower - energy level, they emit electromagnetic radiation corresponding to the energy difference. When they absorb energy and move to a higher level, absorption spectra can be observed. Nuclei, protons, and neutrons are not directly responsible for atomic spectra.

Answer:

e) electrons
