Actually, the answer is that there are ZERO electrons inside a photon!

As far as physicists now understand, electrons and photons are both fundamental particles, which means they are not made up of ANY other particles.

You may have heard that if two very energetic photons crash into each other, then electrons may be produced along with a slew of other particles. However, these particles were not inside of the photons, they were actually created by the energy released by the impact of the two photons.
