The discovery of isotopes in the early 20 th century marked a key moment in the history of physics and led to a much more refined understanding of the atomic nucleus. Isotopes are ‘versions’ of a ...

An isotope is one of two or more atoms of the same chemical element with the same atomic number, occupying the same position on the periodic table and having almost identical chemical behavior, but ...

A collaboration between the groups of Professor Mónica H. Pérez-Temprano at the Institute of Chemical Research of Catalonia ...

The lightest of all elements, hydrogen, is in great demand due to its promising role as a sustainable resource in the energy transition. A team from Leipzig University and TU Dresden, as part of the ...

Deuterium is a stable isotope of hydrogen, which, unlike “normal” hydrogen atoms, or protium, also contains a neutron. The isotope deuterium has one proton, one neutron and one electron. One out of ...

New results from tritium (H3) analysis of waters from the Langtang Valley, Nepal offer insight into the relative ages of different source waters in the glacierized catchment. Since tritium in the ...

Researchers have created hybrid porous organic cages capable of high-performance quantum sieving that could help advance the deuterium/hydrogen isotope separation technologies needed for fusion power.

An element's atomic number defines it. An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So ...
