Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

A proton’s mass is more than just the sum of its parts. And now scientists know just what accounts for the subatomic particle’s heft. Protons are made up of even smaller particles called quarks, so ...

Only 1% of the mass of the proton comes from the Higgs field. ALICE scientists examine a process that could help explain the rest. When protons and nuclei inside the Large Hadron Collider smash ...

The whole is equal to the sum of its constituent parts. That's how everything works, from galaxies to planets to cities to molecules to atoms. If you take all the components of any system and look at ...

If you were to divide the particles that made up your body into smaller and smaller bits, you'd find that at every step along the way -- at least in terms of mass -- the whole was equal to the sum of ...

Are the fundamental constants really constant? Recent investigations have shown that one essential fundamental constant -- namely the mass ratio of protons to electrons -- can have changed only by a ...

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 us ...
