Nucleon - Wikipedia
WebIn physics and chemistry, a nucleon is either a proton or a neutron, considered in its role as a component of an atomic nucleus. The number of nucleons in a nucleus defines the atom's mass number (nucleon number) . Until the 1960s, nucleons were thought to be elementary particles, not made up of smaller parts.

WebWhat are 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. They 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 ...

WebAug 26, 2023 · Nuclei with certain numbers of nucleons, known as magic numbers, are stable against nuclear decay. These numbers of protons or neutrons (2, 8, 20, 28, 50, 82, and 126) make complete shells in the nucleus. These are similar in concept to the stable electron shells observed for the noble gases.

WebThere are two particles that show up in atomic nuclei (both of them composed of quarks) – protons and neutrons. Collectively they are known as nucleons. We give them this generic designation because aside from the differences in their electric charge, they are virtually identical – very close in mass (we will treat them as having equal ...

WebExplain how nuclear force varies with distance. The nuclear force is the force between two or more component parts of an atomic nuclei. The component parts are neutrons and protons, which collectively are called nucleons. Nuclear force is responsible for the binding of protons and neutrons into atomic nuclei.
