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.

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 ...

Certain kinds of atomic nuclei—including those of the hydrogen atoms in a water molecule—c The frequency of the signal ...

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 ...

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 ...
