nucleon
Proton or neutron
A nucleon is a proton or neutron—the particles that make up an atomic nucleus.
The term provides a convenient way to refer to both types collectively: The mass number equals the total nucleons in the nucleus.
Nuclear physics often deals with nucleon interactions and nucleon-nucleon forces.
