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 ...

For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based ...

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 ...

Nuclear physics is a forbidding subject, even for trained physicists. To understand current news and discussion about nuclear science and technology, some background knowledge is required. The high ...

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 ...

An element's atomic number defines it. An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So ...

For example, the atomic number of chlorine is 17. Every chlorine atom has 17 protons and 17 electrons. It has 17 positive charges and 17 negative charges, meaning that it is neutral overall. Atoms of ...
