Ydinpartikkat

Ydinpartikkat, often translated as "nuclear particle" or "atomic particle," is a term used in certain Finnish contexts to refer to subatomic particles that are fundamental constituents of atomic nuclei. This category primarily includes protons and neutrons. Protons carry a positive electric charge and neutrons are electrically neutral. Both are classified as nucleons.

These particles are bound together within the atomic nucleus by the strong nuclear force, one of the four fundamental forces of nature. The number of protons in an atom's nucleus determines its atomic number, which in turn defines the element. The number of neutrons can vary within an element, leading to different isotopes. The mass of an atom is largely determined by the combined number of protons and neutrons in its nucleus. Understanding ydinpartikkat is crucial for comprehending nuclear physics, nuclear reactions, and the properties of matter at the atomic level.
