  1. Positron - Wikipedia

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

  2. Characteristics of Positrons: Antimatter | Open Medscience

    Jul 3, 2024 · Positrons, also known as anti-electrons, are the antimatter counterparts of electrons. They share the same mass and spin as electrons but carry a positive charge.

  3. Positron | Antimatter, Annihilation, Electron | Britannica

    Nov 20, 2025 · The antimatter particles corresponding to electrons, protons, and neutrons are called positrons (e+), antiprotons (p), and antineutrons (n); collectively they are referred to as antiparticles.

  4. Positron: Definition, Charge & Uses in Chemistry Explained

    A positron or antielectron is the antimatter counterpart to an electron. A positron has the equal or same mass as an electron and a spin of 1/2, but it has an electrical charge of +1. When a positron collides …

  5. 31 Facts About Positrons

    Discover 31 fascinating facts about positrons, the antimatter counterparts of electrons, and their role in physics and medical imaging.

  6. Lesson Video: Positrons - Nagwa

    In this video, we will learn how to describe the properties of positrons, the differences between positrons and electrons, and the differences between matter and antimatter.

  7. Positron physics - University of Michigan

    Being anti-electrons, positrons are identical to electrons in all respects except charge. Thus they behave in solids in ways that are identical in many respects.

  8. POSITRON Definition & Meaning - Merriam-Webster

    The meaning of POSITRON is a positively charged particle having the same mass and magnitude of charge as the electron and constituting the antiparticle of the electron —called also antielectron.

  9. The Positron - The Pasayten Institute

    When electrons and positrons collide, they annihilate each other! That is, they convert into a pair of photons, each with 511 keV of energy. Because it is extremely rare for photons to interact with each …

  10. Positrons Definition - Honors Physics Key Term | Fiveable

    Positrons are the antimatter counterparts of electrons, having the same mass but a positive electric charge. They are of great importance in the context of medical applications of radioactivity, …
