In heavy water, each hydrogen atom is indeed heavier, with a neutron as well as a proton in its nucleus. This isotope of hydrogen is called deuterium, and heavy water's more scientific name is ...

While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element ...

A few more examples that recently came to our attention are Klaus Hansen, the scientist who drank heavy water to test if it ...

A team from Leipzig University and TU Dresden, as part of the Hydrogen Isotopes 1,2,3H Research Training Group, has made an ...

All three isotopes of hydrogen have identical chemical properties. This is because the number of electrons determines chemical properties, and all three isotopes have one electron in their atoms.

Hydrogen may be produced from water by electrolysis at substantially greater cost than production from natural gas. The most common isotope of hydrogen is protium (name rarely used, symbol H ...

100ng per compound for hydrogen) which provides powerful information for paloeclimate research, forensic analysis, ecological isotope tracing, oil & gas prospecting and many other organic chemistry ...
