Individual protons and neutrons in atomic nuclei turn out not to behave according to the predictions made by existing theoretical models. This surprising conclusion, reached by an international team ...

HEISENBERG has discussed the hypothesis that the nucleus of an atom is composed of neutrons and protons only, the neutron being regarded as a fundamental entity and not as a combination of an electron ...

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number ...

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 periodic table captures a subtle pattern that runs through the chemical elements, the fundamental building blocks of everything around us: from the aluminium in bike frames to the xenon gas in ...

DEEP in the heart of every atom lurk protons, tiny particles from which the chemical elements were forged, first in the searing heat of the big bang and then in the nuclear furnaces of stars. The ...

Since the beginning of time, human beings have sought to understand what the universe and everything within it is made up of. And while ancient magi and philosophers conceived of a world composed of ...
