The key is to embed a radium atom in a molecule, which contains and intensifies the activities of its electrons, explains ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

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 ...

A new atomic nucleus 149-Lutetium, consisting of 71 protons and 78 neutrons, has been synthesized. A new atomic nucleus 149-Lutetium, consisting of 71 protons and 78 neutrons, has been synthesized in ...

Having good neighbors can be very valuable—even in the atomic world. A team of Amsterdam physicists was able to determine an ...

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 ...

The suspected discovery of an atomic nucleus with four neutrons but no protons has physicists scratching their heads. If confirmed by further experiments, this “tetraneutron” would be the first ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

Scientists have long wondered whether there is a limit to the number of protons and neutrons that can be clustered together to form the nucleus of an atom. A new study comes closer than ever to ...

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 ...

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 ...
