When an Electron and Positron Annihilate?

When an electron and a positron collide, they annihilate resulting in the complete conversion of their rest mass to pure energy (according to the E=mc2 formula) in the form of two oppositely directed 0.511 MeV gamma rays (photons).

What happens when an electron and positron annihilate?

In particle physics, annihilation is the process that occurs when a subatomic particle collides with its respective antiparticle to produce other particles, such as an electron colliding with a positron to produce two photons.

When an electron and positron annihilate the energy released is approximately?

The total amount of energy released when a positron and an electron annihilate is 1.022 MeV, corresponding to the combined rest mass energies of the positron and electron. The energy is released in the form of photons.
