What are the Three Subatomic Particles?

At the end of the article, you will able to describe What are the Three Subatomic Particles, What are their Masses and Charge they have. Let’s Start our discussion.

What are the Three Subatomic Particles?

The three subatomic particles are  – electron, proton, and neutron. With the advancement of science, The Scientists discovered numerous subatomic particle other than these three.  We have listed few Below.

Subatomic particles are main constituents of the atom we call as fundamental particles. The nucleus is the center of an atom.The constituents of the nucleus, both proton, and neutron, are often referred as nucleons.

According to new discoveries,

B meson Antineutrino
Positron Antiproton
Muon Photon
Gluon Alpha particle
down-antiquarks charm antiquark
There are much more we have listed only a few subatomic particles.

Subatomic Particles Definition

The unit (regarded as single and complete) of energy and matter is the subatomic particle. Its composition or constitution of something called as matter. Modern atomic theory says that an atom has fundamental particles: electron, proton, and neutron.

Three Subatomic Particles of an Atom

Electrons always revolve around the nucleus at a very high speed. They are the subatomic particles but they are not a part of nucleons. It has a negative charged and having a very small mass of 1/1840 of the hydrogen atom. Electron decides the chemical and physical properties of an atom.

Protons carry a charge opposite to the electron. It is a subatomic particle found in the nucleus of every atom. The mass of a proton is slightly less than the mass of the neutron. The atomic number is equal to the number of protons.

The hydrogen is the only atom that does not include the neutron.
