What is the difference between electron capture and positron emissions?

In positron emission, a positron (opposite of an electron) is also created in addition to the neutron. In electron capture, the unstable nucleus captures one of the electrons from one of its orbitals and then produces a neutron. This is the key difference between positron emission and electron capture.

What is the difference between positron and electron?

is that electron is (particle) the subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity while positron is (particle) the antimatter equivalent of an electron, having the same mass but a positive charge.

What do positron emission and electron capture have the same effect on a nucleus?

The electron’s capture trigger the emission of an invisible neutrino by the nucleus. 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.

What is the difference between positron and proton?

Main Difference – Proton vs Positron A proton is a subatomic particle having a positive electrical charge (+1). A positron is also a positively charged subatomic particle. The main difference between proton and positron is that the mass of a proton is considerably higher than that of a positron.

Is positron emission the same as positron decay?

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 and photon same?

A photon does not. A positron is the antiparticle of the electron. The photon is its own antiparticle. Just about the only thing they have in common is that they are fundamental particles in the standard model of particle physics.

What is the difference between mass of electron and proton?

proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.
