Nucleon - Wikipedia
In 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.

2021年1月27日 · In chemistry and physics, a nucleon is a proton or a neutron in the atomic nucleus. In contrast, there are free protons and neutrons, which aren’t considered to be nucleons. Protons have a net positive electrical charge, while neutrons are electrically neutral.

Nucleon, either of the subatomic particles, the proton and the neutron, constituting atomic nuclei. Protons (positively charged) and neutrons (uncharged) behave identically under the influence of the short-range nuclear force, both in the way they are bound in nuclei and in the way they are.

Atomic nucleus - Wikipedia
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment.

2024年9月26日 · 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.

Protons and neutrons within the nucleus are called nucleons. Figure \ (\PageIndex {1}\): The atomic nucleus is composed of protons and neutrons. Protons are shown in blue, and neutrons are shown in red. Counts of Nucleons. The number of protons in the nucleus is given by the atomic number, \ (Z\).
Nucleon - Encyclopedia.com
2018年5月14日 · Nucleon is a generic word for the heavy particles that make up the atomic nucleus: the protons and neutrons. It is like the generic word fruit, used to include apples, oranges, and many others, except that the class of nucleons contains only two members.
In order to study the nuclear structure we need to know the constituents of nuclei (the nucleons, that is, protons and neutrons) and treat them as QM objects. From the point of view of QM as we studied until now, we want first to know what is the state of the system (at equilibrium).

Nucleons are the collective term for the protons and neutrons in an atomic nucleus. They are responsible for nearly all of the mass of the atom.
