The branch of physics involved with the study and understanding of the atomic nucleus, including its composition and the forces that bind it together, is called nuclear physics.

Dec 28, 2025 · This branch of physics deals with the structure of the atomic nucleus and the radiation from unstable nuclei.

Mar 26, 2025 · The atomic nucleus is composed of protons and neutrons. Protons and neutrons have approximately the same mass, but protons carry one unit of positive charge and neutrons …

In 1911, Ernest Rutherford discovered that at the core of every atom is a nucleus. Atomic nuclei consist of electrically positive protons and electrically neutral neutrons. These are held …

The atomic nucleus is composed of protons and neutrons ((Figure)). Protons and neutrons have approximately the same mass, but protons carry one unit of positive charge and neutrons …

Explore the technological applications of nuclear physics, from nuclear medicine to lasers, and the challenges still open in understanding matter.

Nuclei are the central core of an atom, containing protons and neutrons, which collectively make up most of the atom's mass. The arrangement and number of these particles in a nucleus …

We have already identified protons as the particles that carry positive charge in the nuclei. However, there are actually two types of particles in the nuclei—the proton and the neutron, …

Surrounding the nucleus is a cloud of electrons, which possess a negative charge that balances the positive charge of the nucleus. The interactions within the nucleus are governed by …

Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should …
