Answer 1

Photons are emitted whenever a massless particle loses energy. For instance, when a captive electron drops to a lower energy level, it emits a photon.

It also also thought that when matter and antimatter mutually annihilate, photons are emitted, although it is possible that baryons may be emitted instead. It should also be noted that particles and anti-particles have been observed to spontaneously generate and annihilate in otherwise "empty" space - thus we should see a large-scale generation of photons from the annihilation where there is empty space, but we do not observe this consistently.

Answer 2

Under the photon theory of light, a photon is a discrete bundle (or quantum) of electromagnetic (or light) energy.

Photons are electrically neutral.

Photons are emitted in many natural processes, e.g., when a charge is accelerated, during a molecular, atomic or nuclear transition to a lower energy level, or when a particle and its antiparticle are annihilated
