For the first time, a research team has successfully produced one of the most neutron-rich isotopes, hydrogen-6, in an ...

The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts.

This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons ... positive protons but one electron so it is a positive ion. Helium ion, two neutrons, two protons and ...

He called it a neutron, and imagined it as a paired proton and electron. There was no evidence for any of these ideas. Chadwick kept the problem in the back of his mind while working on other things.

The team focused on biological crystals, including lysozyme, an enzyme found throughout the living world. What they uncovered ...

In the world of nuclear physics, protons often take the spotlight. But now, for the first time, the neutron has stepped ... nucleon by shooting a high-energy electron at it and watching how ...

Beta decay involves the conversion of a down quark to an up quark. This changes a neutron into a proton plus an electron. The proton stays in the nucleus and the electron leaves the atom with high ...
