Long-held assumptions tell us that atoms with the same number of protons, neutrons and electrons are indistinguishable, but ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei—the center part of atoms, which make up all matter—were more stable ...

For three months in 2019, physicists blasted a beam of electrons at lead atoms that were held in place by foil made of diamond. The team was trying to determine the thickness of the neutron skin, the ...

Physicists have measured the “skin” of an atom for the first time and, perhaps unsurprisingly, it is extremely thin. The measurement may help us understand the properties of neutron stars. Lead-208, ...

Discover the foundational components of an atom: protons, neutrons, and electrons. This video delves into the traditional atom model and reveals its inaccuracies, particularly regarding electron ...

Some atomic nuclei are thin-skinned — they’re surrounded by a slim shell of neutrons. Physicists now know how thick that neutron skin is for one particular type of nucleus. The skin of lead-208 — a ...

There’s a pencil lying on my desk right now. It’s not much to look at, but what if I could zoom way in and see the protons and other itty-bitty stuff inside it? My friend Ryan Corbin told me it would ...

New research suggests a particle inside an atom can lose mass, offering a fresh look at how matter works at the smallest scale.

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...
