What is Nucleon?
A collective term for the protons and neutrons that make up the atomic nucleus. The total number of nucleons equals the mass number of an atom. Strong nuclear forces bind nucleons together in the nucleus, overcoming electrostatic repulsion between protons.

A collective term for the protons and neutrons that make up the atomic nucleus. The total number of nucleons equals the mass number of an atom. Strong nuclear forces bind nucleons together in the nucleus, overcoming electrostatic repulsion between protons.
The nucleon concept is central to: writing nuclear equations (nucleon number conservation), calculating nuclear binding energies (mass defect: Δm = Z×m_p + N×m_n − m_nucleus), designing nuclear reactors (neutron moderation and absorption), nuclear medicine (producing neutron-rich isotopes by neutron…
High-energy nucleons (protons and neutrons used in particle accelerators) are forms of ionising radiation causing biological damage. Neutrons from nuclear reactors and accelerators require polyethylene (hydrogenous) or water shielding for effective attenuation. Activation of materials by neutron bom…
