The other stable isotope, accounting for just about 0.000137 ... though a portion is a by-product of the radioactive decay of hydrogen-3, or tritium. Interestingly, when a volcano erupts, small ...

THE substitution of deuterium for hydrogen has a characteristic effect on the bond lengths in hydrogen compounds, depending on the type of linkage involved. The effect has been described for ionic ...

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 ...

Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium ...

The Section maintains and operates several global isotope data networks for hydrology ... the naturally-occurring radioisotopes of hydrogen (tritium), carbon (carbon-14) and noble gases (helium-3, ...

Stable isotopes have helped uncover migratory routes, trophic levels, and the geographic origin of migratory animals. They can be used on land as well as in the ocean and have revolutionized how ...
