Is a photon an elementary particle?

The photon (Greek: φῶς, phōs, light) is a type of elementary particle. It is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. In 1926, Gilbert N. Lewis popularized the term photon for these energy units.

Which is not elementary particle?

Because mesons have spin of 0 or 1 and are not themselves elementary particles, they are “composite” bosons.

Why Proton is not a fundamental particle?

Since Electrons are leptons,they are fundamental particles of matter. Protons are made up of three quarks ( 2 up and 1 down giving total charge equal to +1) . Since protons are made up of quarks they cannot be termed as fundamental particles. Protons, neutrons and other combinations of quarks are called as hadrons.

What is in a proton?

Protons are positively charged particles found within atomic nuclei. Three quarks make up each proton — two “up” quarks (each with a two-thirds positive charge) and one “down” quark (with a one-third negative charge) — and they are held together by other subatomic particles called gluons, which are massless.

Is a proton a fermion?

A baryon, such as the proton or neutron, contains three fermionic quarks and thus it is a fermion. The nucleus of a carbon-13 atom contains six protons and seven neutrons and is therefore a fermion.

What are the properties of a proton?

A proton is one of three main particles that make up the atom. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.

Why electron proton and neutron are called fundamental particles?

Whereas, electrons are made up of another fundamental particles known as leptons. Earlier, scientist used to believe that electrons protons and neutrons make up the matter and that’s why they were known as fundamental particles.
