Explanation
This question is asking about the behavior of electrons in an atom when the atom emits electromagnetic radiation. Electromagnetic radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of electromagnetic energy. When an atom emits electromagnetic radiation, it means that it is losing energy. This energy is lost when an electron in a higher energy level (or an excited state) falls to a lower energy level, releasing energy in the form of electromagnetic radiation. Therefore, when an atom emits electromagnetic radiation, its electrons move to a lower energy level.
