The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom ...

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 ...

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

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 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 ...

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

Researchers have created three never-before-observed isotopes of magnesium and aluminum. The results not only stake out new territory on the nuclear landscape, but also suggest that variants of ...

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 ...

This week's chemical element is flerovium, which has the atomic symbol, Fl, and the atomic number, 114. This element, originally given the temporary name ununquadium, was formally named in 2012 for ...
