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.

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the ...

Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...

Since the discovery of radioactivity in the 19th century, humanity has been forced to reckon with an uncomfortable but sobering truth: much of the matter we find today will eventually decay away. This ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Researchers just found out where the secret mass of protons is located. Physicists ...

Researchers may have just spotted the elusive, ephemeral nucleus of nitrogen-9 for the first time. With seven protons and two neutrons, the lopsided atomic nucleus of nitrogen-9 pushes the limits of ...

Physicists have long-suspected that the building blocks of protons experienced quantum entanglement. Now, researchers have the first direct evidence — after using a trick to infer subatomic particles' ...
