For years, physicists have mapped the stability of atomic nuclei with remarkable confidence. The periodic table, with its neat rows and columns, hides a more chaotic reality underneath, where protons ...

Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, ...

Dot and cross diagrams help us to model when ions are formed from atoms. Here’s an example using sodium and chlorine. They form ions which bond to form sodium chloride. 2. Work out how many electrons ...

When materials become just one atom thick, melting no longer follows the familiar rules. Instead of jumping straight from solid to liquid, an unusual in-between state emerges, where atomic positions ...

Atoms have a positively-charged nucleus made of protons and neutrons, and negatively-charged electrons that orbit the nucleus in shells. Bonding - (CCEA) Atoms and ions bond with each other in three ...

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 ...
