Antonym For Proton (2024)

FAQs

Antonym For Proton? ›

, (pronounced p-bar) is the antiparticle of the proton. Antiprotons are stable, but they are typically short-lived, since any collision with a proton will cause both particles to be annihilated in a burst of energy.

antiproton, subatomic particle of the same mass as a proton but having a negative electric charge and oppositely directed magnetic moment. It is the proton's antiparticle.

Because they are part of the nucleus, scientists sometimes refer to protons and neutrons as nucleons. Scientists also refer to protons and neutrons as hadrons. Hadron is a term for a composite subatomic particle – a particle that consists of even smaller particles.

Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge.

Photons and antiphotons, because they are uncharged, are considered the same particle. But this criterion would lead to the same conclusion for neutrinos and antineutrinos. These elementary particles have nevertheless an opposite leptonic number. They are different elementary particles.

The antiproton, p. , (pronounced p-bar) is the antiparticle of the proton. Antiprotons are stable, but they are typically short-lived, since any collision with a proton will cause both particles to be annihilated in a burst of energy. Antiproton.

The word proton is Greek for "first", and the name was given to the hydrogen nucleus by Ernest Rutherford in 1920. In previous years, Rutherford had discovered that the hydrogen nucleus (known to be the lightest nucleus) could be extracted from the nuclei of nitrogen by atomic collisions.

Is a neutron the opposite of a proton? ›

Neutrons have a neutral electric charge (neither negative nor positive) and have slightly more mass than positively charged protons. “Free” neutrons are those no longer confined inside a nucleus.

The charge of a proton in units of electronic charge is +1. This is the exact opposite of the charge of an electron which is -1. Despite having both positive and negative particles, most atoms have a neutral charge which forms as the result of the atom having an equal number of protons and electrons.

For example, the antiparticle of the electron is the positron (also known as an antielectron). While the electron has a negative electric charge, the positron has a positive electric charge, and is produced naturally in certain types of radioactive decay.

Protons and neutrons are also called nucleons.

What is the opposite of a photon? - Quora. There really is no antiparticle for a photon. An out of phase photon will cancel it over a limited region, but to cancel everywhere it has to have been emitted from the same source at the same time, meaning nothing was ever really emitted.
