Positron vs. Proton

Positronnoun

(particle) The antimatter equivalent of an electron, having the same mass but a positive charge

Positronnoun

an elementary particle with positive charge; interaction of a positron and an electron results in annihilation

Positron

The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1 e, a spin of 1/2 (the same as the electron), and has the same mass as an electron.

Protonnoun

(particle) A positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element, composed of two up quarks and a down quark.

Protonnoun

a stable particle with positive charge equal to the negative charge of an electron

Proton

A proton is a subatomic particle, symbol p or p+, with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as (particles present in atomic nuclei).
