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. An ...

For the first time those little numbers that appear beneath some of the commonest elements in the periodic table boxes are about to change from a single value to an interval of numbers An ...

A major outcome of the April 2010 Nuclear Security Summit in Washington, DC, was the commitment by 47 nations to collaborate in developing new technologies that require neither highly enriched uranium ...

This clip shows how carbon is made up from sub-atomic particles. Electron shells are mentioned. Two extra neutrons are added to make an unstable isotope which explodes at the end. This clip could be ...

Known as “islands of inversion,” these odd regions are found among a sea of normal nuclei. Now, a new island may have been spotted in surprising circumstances.

For years, physicists have mapped the stability of atomic nuclei with remarkable confidence. The periodic table, with its ...

An international research collaboration has provided experimental and theoretical evidence for the existence of the magic number of six in carbon isotopes. The researchers experimentally determined ...

Here, we examine the nucleus more closely, to prepare us to study how BNPP would work, reactor accidents, the toxic vicinity of an operating reactor, and the nuclear waste that will be lethally ...
