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.

Why do some elements decay in minutes, while others last billions of years? Certain "magic numbers" of nuclear particles may make all the difference.

Hadrons count among their number the familiar protons and neutrons that make up our atoms, but they are much more than that. In the early 1900s, physicists were trying to find the source of a ...

A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even ...

Billions of times each minute, the Large Hadron Collider (LHC) smashes protons together, unleashing a maelstrom of energy that crystallizes into more protons, neutrons, and less familiar cousins of ...

Scientists have almost completed the development of the High Resolution Neutron Spectrometer (HRNS). The system will be used ...
