Isotope and nuclide are closely related terms. When one speaks of isotopes, they are referring to the set of nuclides that have the same number of protons. Nuclide is a more general term, referring to a nuclear species that may or may not be isotopes of a single element. Examples: ...
Described in the simplest form, the measurement of a number N ( i E) of atoms of an isotope i E of an element E, can be performed by adding a known number of atoms N ( j E) of another isotope j E (= a "spike") of the same element, and measuring the number-ratio N ( i ...
The atomic number dictate the number of protons while the mass number gives the total protons and neutrons in the nucleus. Meanwhile, isotopes are variants of an element characterized as having a different mass number. A representation of an isot...

Hence, the generally accepted interpretation of the eclogite xenolith oxygen isotope signatures is that they represent a protolith that experienced alteration processes in the crust before subduction into the mantle. The range in δ18O values of eclogites is taken to reflect derivation from different ...
The 222Rn isotope has been more widely used because of its longer half-life and the greater relative abundance in the free atmosphere. For near ground level, tracer studies have been based on thoron mainly because of its short half-life (55.6 s). Since the ocean represents a poor radon ...
