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 ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...

How is the table organized? The Periodic Table, first compiled by Russian chemist Dmitri Mendeleyev, is organized by the number of protons in the nucleus of each element's atom, known as the atomic ...

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 ...

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

Physicists studying atomic spin surprised themselves by discovering that spinning protons bizarrely change direction when they crash into larger particles, like the nuclei of gold atoms. On a pool ...

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 ...

Standard atomic weights, those numbers emblazoned under the elements on the periodic table, were once thought of as unchanging constants of nature. But researchers have tweaked the atomic weights of ...
