nukleony
Nukleony is a term used in nuclear physics to refer to the particles that reside within the atomic nucleus. There are two types of nukleony: protons and neutrons. Protons carry a positive electric charge, while neutrons have no electric charge. Both protons and neutrons have approximately the same mass, which is significantly larger than the mass of an electron.
The number of protons in an atom's nucleus determines its atomic number and, consequently, its chemical element.
Protons and neutrons are not fundamental particles; they are composed of smaller particles called quarks. Specifically,
