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

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 ...

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 ...

The ratios of strontium isotopes in fossil shark teeth can be used to better understand how coastal environments evolved in ...

This photo taken on Dec 26, 2024 shows workers adjusting and testing China's first commercial reactor device for the online irradiation production of isotopes at the Qinshan Nuclear Power Base ...

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 ...

The map is available for public use through open access. It is the first bioavailable strontium isotope map to show predicted strontium isotope ratios across all of Sub-Saharan Africa. Strontium ...

The questions in this quiz are suitable for GCSE physics students studying structure of the atom, atoms and isotopes and ions. If you struggled with the quiz, don't panic - we've got you!

Researchers mapped predicted bioavailable strontium isotope ratios across Sub-Saharan Africa. Matching values from the map against those observed in artifacts and plant, animal, and human remains will ...
