Now, researchers in the US and South Korea have used a neutron beam to differentiate between genuine antique coins and fakes.

These nuclei had specific numbers of protons or neutrons, or magic numbers, as physicist Eugene Wigner called them. The race ...

He’s a quantum physicist at Washington State University. He told me that protons – along with neutrons – form the nucleus in the middle of an atom. “Atoms make up all the stuff that we see ...

This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons), 17 of which are protons. It also tells us that chlorine has 18 neutrons (35 - 17) and, as the number of ...

The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable atom has a net charge of 0. In other words, it has an equal number of protons and ...

The team suggests that energetic photons generated by newly forming black holes or neutron stars transmute protons within ejected stellar material into neutrons, thereby providing ideal conditions for ...

At the interface of the jet with the stellar material, high-energy photons (that is, light) can interact with atomic nuclei, transmuting protons to neutrons. Existing atomic nuclei may also be ...
