Web21 feb. 2024 · Explanation: The positron is similar to the electron but with an opposite charge. When the positron and the electron collide together, annihilation occurs where the electron and the positron disappears and two photons in form of gamma rays are produced. They are said to converted all their rest mass energy into kinetic energy. The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. It has an electric charge of +1 e, a spin of 1/2 (the same as the electron), and the same mass as an electron. When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it … Meer weergeven Theory In 1928, Paul Dirac published a paper proposing that electrons can have both a positive and negative charge.

Web5 jul. 2024 · A positron is a particle with the same mass as an electron, but with a positive charge. Like the beta particle, a positron is immediately ejected from the nucleus upon its formation. The symbol for a positron in an equation is e + 0 1. For example, potassium-38 emits a positron, becoming argon-38. K38 19 → Ar38 18 + e0 1 can kidney stones affect your gfr reading
