Derivative terms: Isotopic



Definition of Isotope

1. Noun. (physics) Any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei. As a consequence, atoms for the same isotope will have the same atomic number but a different mass number (atomic weight). ¹

2. Verb. (topology transitive) To define or demonstrate an isotopy of (one map with another). ¹

Medical Definition of Isotope

1. One of several nuclides having the same number of protons in their nuclei and hence having the same atomic number, but differing in the number of neutrons and therefore, in the mass number. Almost identical chemical properties exist between isotopes of a particular element. The use of this term as a synonym for nuclide is to be discouraged. (16 Dec 1997)
