The atomic nucleus is the small, dense region at the center of an atom, composed of protons and neutrons, which together account for nearly all of the atom's mass. Its stability and interactions are governed by the strong nuclear force, which is much stronger than the electromagnetic force that would otherwise cause the positively charged protons to repel each other.

Protons and neutrons are the fundamental particles that make up the nucleus of an atom, with protons carrying a positive charge and neutrons being neutral. Together, they determine the atomic mass and the identity of the element, playing a crucial role in the structure and stability of matter.

Stability refers to the ability of a system or entity to maintain its state or return to it after a disturbance, ensuring continuity and predictability over time. It is a fundamental characteristic sought in various fields such as physics, economics, and social sciences, where it implies resilience and equilibrium.

The strong nuclear force is the fundamental interaction responsible for holding atomic nuclei together, overcoming the electromagnetic repulsion between protons. It acts over very short ranges, approximately the size of an atomic nucleus, and is the strongest of the four fundamental forces in nature.

Electromagnetic force is one of the four fundamental forces of nature, responsible for interactions between charged particles and the behavior of electromagnetic fields. It governs a wide range of phenomena from atomic bonding and chemical reactions to the propagation of light and electromagnetic waves.
