High-pressure pump–probe experiments reveal the mechanism of excited-state proton-coupled electron transfer and a shift from stepwise to concerted pathways. Nature Chemistry , 2025; DOI: 10.1038 ...

Proton’s mass radius is apparently shorter than its charge radius The quarks that give it charge aren't hanging out with the gluons that provide mass.

Our universe is filled with particles, such as electrons and protons, which make up all the stuff on our planet and beyond: ...

In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei.

This weak charge is predicted by the Standard Model to be about -0.989 for neutrons and about + 0.071 for protons (+) and electrons (-), as measured in elementary charges.

The elementary charge of the proton is 1.602192 x 10^–19 coulombs (C). This is the exact equal and opposite of the charge of an electron, which is — 1.602192 x 10^-19 coulombs.

Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge. Since opposite charges attract, ...

NEWPORT NEWS, VA, Sept. 17, 2013 – Researchers have made the first experimental determination of the weak charge of the proton in research carried out at the Department of Energy's Thomas ...
