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.

Hypernuclei are exotic nuclei formed by a mix of protons, neutrons and hyperons, the latter being unstable particles ...

The strong force holds together quarks, the fundamental particles that make up the protons and neutrons of the atomic nucleus, and further holds together protons and neutrons to form atomic nuclei.

A neutron star's almost incomprehensible density causes protons and electrons to combine into neutrons—the process that gives such stars their name. The composition of their cores is unknown ...

In a groundbreaking discovery, scientists have revealed an unprecedented map of the forces acting within a proton. This map ...

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.

“BNCT requires epithermal neutrons, and they are best obtained by irradiating a lithium target with a low energy, high current proton beam. But at that time, there was no suitable proton ...

The valve counter consists of a small ionisation chamber connected to an amplifier, and the sudden production of ions by the entry of a particle, such as a proton ... of a neutron in passing ...

They have a radius of around 1 × 10 10 metres. 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 ...
