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.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you want to probe the frontiers of fundamental physics, you have to ...

Look around you (or, if you’re sight impaired, touch something). Everything solid, liquid, or gas that you see and feel is made of matter. We sometimes call it “normal” matter, though with dark matter ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

The film discusses the dual nature of atomic energy, likening it to the sun, which can both sustain and destroy life. It explains the structure of atoms and the process of nuclear fission, leading to ...

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 ...

Protons make up most of the visible universe. Now, in a new study published in the August 18 issue of the journal Nature, scientists find that because of the strange nature of quantum physics, protons ...

Water molecules are so attracted to each other that even after the balloon pops, the water molecules stay together keeping the shape of the balloon. In the water molecule, the oxygen and hydrogen ...
