In the case of lead-208—the heaviest stable isotope known so far—a team of researchers led by physicist Jack Henderson ...

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 ...

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.

Atoms are very small. They have a radius of around 1 × 10-10 metres.

This Section implements all activities of the IAEA's Water Resources Programme, which promotes and transfers know-how on the use of isotope hydrology as an effective tool for water resources ...

Charge carriers have been confined by exploiting the small difference between the bandgap energies of the two naturally occurring stable isotopes of carbon. Many high-speed electronic and ...
