Subatomic particle, any of various self-contained units of matter or energy that are the fundamental constituents of all matter. They include electrons, protons, neutrons, quarks, muons, and neutrinos, as well as antimatter particles such as positrons.
The subatomic particles considered important in the understanding of chemistry are the electron, the proton, and the neutron. Nuclear physics deals with how protons and neutrons arrange themselves in nuclei.
A Subatomic particle is nothing but a particle which is smaller than an atom in size. Typically, an atom can be broken down into three subatomic particles, namely: protons, electrons, and neutrons. What are Subatomic Particles?
By definition, subatomic particles are smaller than an atom. Atoms consist of three subatomic particles : protons , neutrons , and electrons . Each atom has a nucleus that contains protons and neutrons and has a positive electrical charge.
The atom consists of discrete particles that govern its chemical and physical behavior. Each atom of an element contains the same number of protons, which is the atomic number ( Z ). Neutral atoms have the same number of electrons and protons.
Learn what subatomic particles are and all the different types that exist according to the standard model of modern physics.
What are Subatomic Particles? A subatomic particle is smaller than an atom and cannot be seen by our naked eyes. There are three subatomic particles called electrons, protons, and neutrons. Electrons have a negative charge, protons have a positive charge, neutrons have no charge.
