Like everything we see in the world, isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element. Isotopes are forms of a chemical element with ...

Isotope geochemistry investigates the distribution and variations in the relative abundances of isotopes—both stable and radiogenic—in natural materials. By utilising high‐precision analytical ...

Researchers analyze the ratios of calcium isotopes in bones and fossils to learn more about what dinosaurs once ate. Credit: ...

The discovery of stable ''isotopes" began with J. J. Thomson's identification of neon-22 in 1912 (Bievre et al., 1984). More than 90 naturally occurring elements have been identified on the earth; ...
