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.

Scientists found an unexpected nuclear energy shift in radioactive lanthanum isotopes, challenging existing models and ...

The periodic table organizes chemical elements based on atomic weight, electron configurations, and chemical properties, ...

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 ...

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, precisely measured atomic masses of ...

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 ...

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 ...

Heavy water is a form of water with a unique atomic structure and properties coveted ... with a neutron as well as a proton in its nucleus. This isotope of hydrogen is called deuterium, and ...
