In our previous sessions, we have studied in detail the protons, neutrons, particles in the nucleus, and mass number. Positively charged subatomic particles are known as protons. Neutrons are subatomic particles that are neutrally charged. Nucleons are the particles found in the nucleus of atoms. In this article, let us know in detail about nucleons and their properties.

What areΒ Nucleons?
A nucleon is one of the particles of the atomic nucleus. Each atomic nucleus includes one or more Nucleons. These are surrounded by one or more electrons. TheyΒ occupy a small space within the nucleus. Every atom is made up of nucleons which are further divided into electrons, protons, and neutrons that orbit the nucleus. An atom is just like a mini solar system, with electrons orbiting a central star which is the nucleus, composed of nucleons.
Protons and neutrons are the best-known components of atomic nuclei. They can be found on their own not being part of the larger nucleus. A proton is the nucleus of the hydrogen-1 atom on its own which is the most abundant isotope of hydrogen.
Binding Energy Per Nucleon
Nuclei consist of neutrons and protons, but the mass of the nucleus is less than the sum of individual masses of the protons and neutrons. The difference is the measure of binding energy per nucleon that holds the nucleons together. The binding energy can be determined from the Einstein relationship:
Nuclear binding energy = Ξmc2
Ξm = 0.0304 u for alpha particles and gives binding energy of 28.3 MeV.
Properties of Nucleons
A neutron is not stable on its own, but it can be found in nuclear reactions and used in scientific analysis. Both the proton and neutron consist of three quarks. The proton has two up quarks (the lightest of all quarks and aΒ major constituent of matter and a type of elementary particle) and one down quark (the second lightest), while a neutron is made up of one up quark and two down quarks.
TheseΒ are an integral part of the atomic nucleus since they cannot exist as independent nucleons. Nucleons are composite particles composed of three quarks bound together by the strong interaction. The atomic nucleus holds the nucleons with a strong force. However, when the force is broken, it can produce a lot of power, and that power is termed as nuclear energy which is similar to what is used in nuclear bombs. Nucleons present in radioactive decay substances such as uranium can be harmful since it can spread alpha radiation in a few seconds.
