Japanese scientists have made a new (nu?) periodic table organized by the number of protons in the nucleus instead of the element’s number of electrons. They call it the Nucletouch table, and where ...

The rare radioactive substance made its way from the United States to Russia on a commercial flight in June 2009. Customs officers balked at accepting the package, which was ensconced in lead ...

The recent discovery of elements 113 and 115 will tell us more about the structure of the nucleus and the possible existence of the “island of stability”. The heaviest elements The periodic table of ...

An element is defined according to the number of protons contained inside the nucleus of each atom. No two elements have the same number of protons, hence each element has a unique atomic number. The ...

At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature. In fact, they ...

For new, human-made heavy elements on the periodic table, being “too ‘big’ for your own good” often means instability and a fleeting existence. The more protons and neutrons scientists squeeze ...

Wielding proton beams and lasers, physicists have for the first time unlocked one of the key secrets of the rarest naturally occurring element on Earth: astatine. It's so rare that until recently, ...

SINCE the publication of our paper 1 on the disintegration of elements by fast protons, we have examined some of the light elements more carefully, using much thinner mica windows than we had ...
