The electron, proton, and neutron are elementary particles that make up atoms. Each of these particles has different properties and is characterized by different fundamental properties. Here are their symbols and basic properties:
Electron: Symbol: e⁻ Electric Charge: -1 elementary charge Mass: Approximately 9.10938356 x 10^-31 kilograms
Proton: Symbol: p⁺ Electric Charge: +1 elementary charge Mass: Approximately 1.67262192369 x 10^-27 kilograms
Neutron: Symbol: n⁰ Electric Charge: No charge (neutral) Mass: Approximately 1.67492749804 x 10^-27 kilograms
It's important to note that the formula you are referring to is not applicable to these particles. They are fundamental particles and are not composed of smaller constituents. However, they do interact with other particles and fields through fundamental forces such as electromagnetic and strong nuclear forces.
