Nucleons are composite particles made up of protons and neutrons. The protons and neutrons collectively present in the nucleus of an atom are called nucleons. The nucleons occupy very small space inside the nucleus. Nucleons are an important part of an atomic nucleus and therefore, they are important in particle physics. Every mass in the matter is made up of atoms and molecules, and atoms are in turn compose of nucleons. Every atom is made of nucleons, which are further divided into protons, neutrons and electrons, which orbit the nucleus. An atom can be viewed as a miniature solar system, with "planets" (electrons) orbiting a central "star" (the nucleus, composed of nucleons).
Electrons only have 1/1836 the mass of protons, and 1/1837 the mass of neutrons. Neutrons and protons have about the same mass. Since nucleons are an integral part of the atomic nucleus there will be no independent nucleons. The atomic nucleus of the particles strongly holds the nucleons with a strong force. However, when the force is broken it can generate a lot of power, and that power is generally termed as the nuclear energy which is very similar to what is used in nuclear bombs. Nucleons found in radioactive decay substances like uranium can be harmful to all life as it can spread alpha radiation in just a matter of second.
Nuclear forces are attractive forces which exist in between protons and neutrons, neutron and neutron, proton and proton. It is the strongest force. It is much stronger than gravitational and electrostatic forces due to positive charge on protons. This strong force is about 100 times stronger than the electromagnetic force, but it only operates on extremely tiny distances, i.e. the scale of nucleons. However, when its power is released, by breaking or fusing together atomic nuclei, the results are incredible as in the case of atomic bombs, or the Sun, which both operate by manipulating nucleons. This is commonly known as "Nuclear energy." Nucleons found in radioactive decay substances like uranium can be harmful to the life of people as it can spread alpha radiation in just a matter of seconds.
Corresponding to most kinds of particles, there is an associated antiparticle with the same mass and opposite electric charge. For example, the antiparticle of the electron is the positively charged anti-electron, or positron, which is produced naturally in certain types of radioactive decay. Both of the nucleons have corresponding antiparticles called anitnucleons.
These antimatter particles have the same mass and opposite charge as the proton and neutron respectively, and they interact in the same way. If there is a difference, it is too small to measure in all experiments to date. In particular, anti-nucleons can bind into an "anti-nucleus". So far, scientists have created anti-deuterium and antihelium-3 nuclei.
