Does Light Excited Electrons?

An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle.

Where does light energy excite electrons?

Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced.

Are there electrons in lighting?

A: Light is definitely not a molecule. It has no rest mass, no protons, no neutrons, no electrons. When some light is absorbed by something else (a molecule, for example) the light's energy, momentum, and angular momentum are transferred to that object.
