Unstable atoms emit fast-moving particles that can damage cells in the human body. Some atoms are far more unstable than ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Most of the mass and all of the positive charge of an atom is in the nucleus. Most of an atom is empty space, (a vacuum). In 1897, ...

Since the atomic nucleus was first proposed in 1911, physicists simply assumed it was round. But are the nuclei of atoms really round? Intuitively this shape makes sense and physicists believed it ...

Researchers have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom.

The difference lies in the structure of the atom's nucleus, with certain "magic numbers" of nuclear particles making some isotopes especially resistant to radioactive decay. So what are these magic ...

Quantum entanglement – once dismissed by Albert Einstein as "spooky action at a distance" – has long captured the public ...

Scientists in Finland have measured the heaviest known nucleus to undergo proton emission, discovering the rare isotope 188-astatine. It exhibits a unique shape and may reveal a new kind of nuclear ...
