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, we explore the existence of neutrons and their transformation into protons. We discuss why free neutrons are ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. How do atoms form? – Joshua, age 7, Shoreview, ...

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 journey of the elements starts in the earliest moments of the Big Bang, when our universe was only a few seconds to a few minutes old. When you purchase through links on our site, we may earn an ...

OAK RIDGE, Tenn. — Examining the smallest parts of the universe often takes the biggest kinds of equipment. At Oak Ridge National Laboratory, a unique piece of equipment the size of a building is ...

Scientists are holding up a 'mirror' to protons and neutrons to learn more about the particles that build our visible universe. The MARATHON experiment has accessed new details about these particles' ...

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 ...

Protons can hold an elementary particle heavier than themselves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Protons may have more "charm" ...

Detections of gravitational waves from merging neutron stars tipped off researchers here on Earth that it should be possible to predict how neutrons interact with atomic nuclei. Nuclear power is ...
