Neutronszámú

Neutronszámú is a term that refers to the number of neutrons within the nucleus of an atom. This quantity, along with the number of protons, defines an atom's specific isotope. The number of protons, also known as the atomic number, determines the element itself. While the number of protons remains constant for a given element, the number of neutrons can vary, leading to different isotopes of the same element. For example, hydrogen has three common isotopes: protium, deuterium, and tritium. Protium has one proton and zero neutrons. Deuterium has one proton and one neutron. Tritium has one proton and two neutrons. The sum of the number of protons and neutrons in an atom's nucleus is called the mass number. The neutronszámú plays a crucial role in nuclear stability. The ratio of neutrons to protons influences whether an atomic nucleus is stable or radioactive. Unstable nuclei tend to undergo radioactive decay to reach a more stable configuration. Understanding the neutronszámú is fundamental in fields such as nuclear physics, chemistry, and nuclear medicine.
