Nuclides
Definition and meaning of Nuclides in chemistry.
Nuclides are distinct types of atoms characterized by the specific number of protons and neutrons residing in their atomic nuclei. This term is used broadly to distinguish between different isotopes of elements and to identify the exact composition of a nucleus.
In more detail
While the term isotope refers specifically to atoms of the identical element with different numbers of neutrons, nuclide is a more general and inclusive term for any specific nuclear configuration. A nuclide is typically denoted by the chemical symbol of the element placed alongside its exact mass number. Identifying specific nuclides is crucial in nuclear chemistry and physics for tracking complex radioactive decay pathways and calculating nuclear binding energy accurately.

Carbon-12 and carbon-14 are two entirely different nuclides of the element carbon, possessing six and eight neutrons respectively in their atomic nuclei.
Frequently asked questions
What is the difference between a nuclide and an isotope?
Isotope refers to atoms of the same element with varying neutron counts, whereas nuclide refers to any specific atomic nucleus regardless of the element.
