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 ...

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 ...

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 ...

FOR twelve years now, nuclear physicists have been able to produce in their laboratories a slow release of usable amounts of atomic energy, by transmuting stable atoms of the ordinary chemical ...

For most atomic nuclei, the maximum number of neutrons that can be bound is unknown. The discovery of two neutron-rich nuclei — and the confirmed absence of others — might help solve this conundrum.

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 ...
