There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.

Protons (positively charged) and neutrons make up the core nucleus of the atom (with no charge). Negatively charged electrons go around the nucleus in orbits or shells that are made up of imaginary routes.
The protons, neutrons, and electrons that make up an atom are incredibly small particles.
Proton
- A proton is a subatomic particle with a mass of one and a positive charge (positive charge).
- The sign p or p+ is used to represent a proton. Protons are found in the nucleus of each atom.
- An element's atomic number is the number of protons in each atom.
- Protons are represented by the nucleus of a hydrogen atom, or the H+ ion.
Neutron
- The neutron is a one-dimensional subatomic particle having a mass of one and a charge of zero.
- In the atomic nucleus, neutrons are present with protons.
- While an atom's element is determined by its number of protons, its isotope is determined by the number of neutrons.
- Nuclear fission and fusion are two nuclear processes that produce a huge number of neutrons.
- Because it has a spin of 1/2, a neutron is considered a sort of fermion.
Electron
- A stable subatomic particle with a negative electrical charge is called an electron.
- A unit of negative charge is carried by each electron (1.602 x 10-19 coulomb).
- The electron is represented by the symbol e–. In nature, electrons are found both free and bonded within atoms (free electrons).
- 9.10938 x 10-31 kg is the mass of an electron.
