You often hear that each nucleon, like a proton or neutron, has three quarks inside of it, and that the quarks exchange gluons. But that isn’t the full picture at all.

Atoms are very small. 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 ...

The model predicts the formation of distinct electron shells with different capacities: the first can fit the maximum of 2 electrons, with 8 on the second, 18 on the third, and so on.

The emission of beta radiation provides evidence that neutrons and protons are made up of quarks. Beta (\(\beta^-\)) decay is the release of an electron by the change of a neutron to a proton. The ...

Baryons are subatomic particles made up of an odd number of quarks. Protons and neutrons found at the center of atoms are a ...

Three William & Mary nuclear physicists are part of a team of scientists probing the strongest force in the universe, using a novel method of accessing the space between protons and neutrons in dense ...

All atoms contain antimatter The first three subatomic particles you ever learned about were likely the proton, neutron and electron. These particles make up the atoms that form our bodies and the ...
