The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision ...

Different neutron states could explain why different experiments produce different figures for how long neutrons survive ...

Nuclear fission has powered our world and medical advancements for decades. What exactly happens when an atom's nucleus splits into two parts?

The atomic nucleus is made up of protons and neutrons, particles that exist through ... of a specific particle being created in an electron or proton collision with the nucleus.

Axions: from soap to dark matter Protons, neutrons, electrons, photons -- most of us are familiar with the names of at least some of these tiny particles. The axion is lesser known, and for a good ...

At low energies, the nucleus of an atom appears to behave as if it were made of protons and neutrons, but when the energies are higher, the influence of quarks and gluons becomes "visible" to the ...

If we figure out how to harness this effectively and efficiently, this is it. This is the end. This is the solution,” an expert tells us.

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons ... in an electron or proton ...
