In positron emission, also called positive beta decay (β+-decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but of opposite charge. Is positron emission the same as positron decay? The main difference between proton and positron is that the mass of a proton is considerably higher than that of a positron. A positron is also a positively charged subatomic particle.

Main Difference – Proton vs Positron A proton is a subatomic particle having a positive electrical charge (+1). What is the difference between positron and proton? The capture of an electron has the same effect on a nucleus as the emission of a positron: one of its protons transforms into a neutron, diminishing the global electric charge of the nucleus by 1 unit. The electron’s capture trigger the emission of an invisible neutrino by the nucleus. READ ALSO: How can we make the world better for kids?
