The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

A team of scientists, including four at The Johns Hopkins University, has discovered two new subatomic particles, rare but important relatives of the familiar, commonplace proton and neutron. Named ...

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" ...

Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...

Physicists have long-suspected that the building blocks of protons experienced quantum entanglement. Now, researchers have the first direct evidence — after using a trick to infer subatomic particles' ...

An ancient crocodile’s last meal might never have come to light were it not for researchers deciding to scan the rock-embedded fossil with a beam of neutrons. The scientists had set out to see if ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

A new study identifies a transition in the strong nuclear force that illuminates the structure of a neutron star's core. Most ordinary matter is held together by an invisible subatomic glue known as ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...

Almost anything is possible — at least for a subatomic particle. One of the many mystifying consequences of quantum mechanics — the rules that govern the behavior of tiny subatomic particles — is that ...
