Nuclide
A nuclide is a specific kind of atom defined by the number of protons and neutrons in its nucleus. Each nuclide has a unique combination, which determines its identity and properties. For example, carbon-12 and carbon-14 are different nuclides of carbon, distinguished by their neutron count. Nuclides can be stable or radioactive; radioactive ones decay over time, emitting energy. Understanding nuclides helps scientists study element behavior, radioactive dating, nuclear energy, and medical applications such as imaging and treatment. In essence, a nuclide is a particular form of an element distinguished by its nuclear composition.
