Question

1. how is light formed? * 4 points ground state excited state emission spectrum lines a. electrons absorb photons and move to higher energy levels. b. electrons release energy when moving to lower energy levels. c. protons and neutrons collide inside the nucleus. d. atoms spontaneously split into ions.

Explanation:

Light is formed when electrons in an atom move from a higher - energy excited state to a lower - energy ground state and release energy in the form of photons. Option A describes the absorption process, not light - formation. Option C involves nuclear processes not related to light formation. Option D is about ionization and not related to light formation.

Answer:

B. Electrons release energy when moving to lower energy levels.
