Only quarks have a smaller charge, being a third or two-thirds of the elementary charge. The elementary charge of the proton is 1.602192 x 10^–19 coulombs (C).

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.

Weak charge of proton determined for first time Date: September 17, 2013 Source: DOE/Thomas Jefferson National Accelerator Facility Summary: Researchers have made the first experimental ...

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, ...

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.

David Armstrong, Chancellor Professor of Physics at William & Mary and chair of the department, is a member of the Qweak Collaboration, a collection of scientists who recorded the first ever direct ...

A new type of experimental proton battery is built with entirely organic components, making it much more environmentally friendly than most. On top of that, it can also be charged in a matter of ...

Protons are no one-trick ponies. Although famous for their positive electric charge, the particles also carry an analogous, lesser-known charge, called the weak charge. Now, physicists have made ...

Weak link: the Q WEAK experiment (Courtesy: Jefferson Lab). The weak charge of the proton has been measure to high-precision for the first time. The work was done at the Thomas Jefferson National ...
