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.

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue examines how atomic structure determines reactivity. Meet Theo Gray, chemist and author, who ...

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 ...

Particle accelerator technology has crested a new wave. For the first time, scientists have shown that electrons can gain energy by surfing waves kicked up by protons shot through plasma. In the ...

For the first time, researchers have reported a 3D metal-organic framework (MOF) that can conduct both electrons and protons (J. Am. Chem. Soc. 2024, DOI: 10.1021/jacs.4c13792). Materials mixing ...

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...

Physicists working at the CERN particle physics lab said they detected a slight but significant difference in how particles of matter and antimatter decay. By Kenneth Chang Understanding why matter ...
