Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. Protons are tiny subatomic particles that, along with neutrons, form the nucleus of an atom. The ...

This is a great question. The answer is well beyond an introduction to chemistry for middle school, but one thing you can say is that there is a force called the “Strong Force,” which holds protons ...

Scientists are using “trapped ions” in highly precise experiments to search for a new, fifth force of nature that could help ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

The idea of powering a house with a single atom might seem like science fiction, but recent advancements in nuclear physics ...

An atom consists of a nucleus containing protons and neutrons, surrounded by electrons. are very small, they have a radius of around 0.1 nanometres (1 × 10-10 metres).

While gluons are responsible for generating most of the visible mass in the universe, their role inside nuclei remains poorly ...

That’s what holds together an atom’s nucleus. It’s why protons stick together – even though things with the same charge repel each other. “Those quarks and gluons only get you part of ...

The protons in the nucleus also give rise to an atom’s characteristics. Even though the atom is visible, it’s still not the easiest to see. If you look very closely at the center of the photo ...
