Question

question 5 of 30 what happens when an electron absorbs photons? a. it changes into a neutron and falls into the nucleus. b. it changes into an alpha particle and is ejected from the atom. c. it moves to a higher energy level. d. it falls to a lower energy level.

Explanation:

• Option A: Electron turning into a neutron and falling into the nucleus is not related to photon absorption; this is a process in electron capture (a type of nuclear decay), so A is incorrect.
• Option B: An alpha particle is a helium nucleus (2 protons, 2 neutrons), and electrons can't turn into alpha particles. Ejection of electrons (like in photoelectric effect) is different from this, so B is incorrect.
• Option C: When an electron absorbs a photon (which carries energy), it gains energy. This extra energy allows it to move from its current energy level to a higher (more energetic) energy level (also called an excited state). This is a fundamental concept in atomic structure and quantum mechanics related to electron energy levels.
• Option D: Falling to a lower energy level happens when an electron emits a photon (releases energy), not absorbs. So D is incorrect.

Answer:

C. It moves to a higher energy level.
