Gaining insight could help understand the timing and process of life's emergence. A research team led by a Rutgers-New ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...

This isotope of hydrogen is called deuterium ... Nuclear reactors that use heavy water can employ a form of uranium commonly found in nature (U-238) rather than requiring so-called enriched ...

The stable isotope concentrations of a molecular compound or material are presented in ratio form as the molar ratio of the heavy-to-light isotopes. Since this ratio is small, we typically present ...

Isotopes have the same number of protons but differ in their number of neutrons, resulting in different masses. The lighter form is generally the more common one (Hobson & Wassenaar 2008).

and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element. For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written ...
