Describe how light is emitted from an atom. a) as protons absorb energy they travel from the nucleus through the atom emitting light along the way. b) the light is emitted when energy from sunlight is absorbed by the atom to excite a neutron into a higher level. c) when the nucleus absorbs sunlight, photons are energized and move to a higher energy level and are then released. d) light is emitted from an atom as an electron falls from an excited state to the ground state releasing a photon.
