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 ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...

For surfers, it's not enough just to wait for the right wave: they still have to know how to catch it. As it turns out, one challenge faced by surfers also applies to protons. An experiment recently ...

According to the classical model of nuclear structure, the internal structure of nucleons should not change if they are bound into atomic nuclei. But it was discovered 35 years ago that quarks inside ...

Why do some elements decay in minutes, while others last billions of years? Certain "magic numbers" of nuclear particles may ...

Collisions of lead nuclei take place under extreme physical conditions. Their course can be described using a model which assumes that the transforming, extremely hot matter - the quark-gluon plasma - ...

In 2002, a team of Russian and American scientists created the first ever atom of oganesson, which is the heaviest chemical element ever recorded to date. With an atomic number of 118, oganesson ...
