Question

1. what causes an absorption spectrum? * 4 points ground state excited state emission spectrum lines light light a. electrons releasing photons b. electrons absorbing photons to jump energy levels c. protons absorbing neutrons d. atoms losing electrons completely

Explanation:

An absorption spectrum occurs when electrons in an atom absorb photons of specific energies and jump to higher energy levels. This process leads to dark lines in the spectrum corresponding to the absorbed photon energies. Electrons releasing photons creates an emission spectrum. Protons absorbing neutrons is related to nuclear - processes and not absorption spectra. Atoms losing electrons completely is ionization and not related to absorption spectra.

Answer:

B. Electrons absorbing photons to jump energy levels
