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.

We know a proton paired with an electron makes hydrogen—the first element on the periodic table and the fuel that allows stars to shine. ... In fact, the proton’s “weak charge” radius, ...

He called it a neutron, and imagined it as a paired proton and electron. There was no evidence for any of these ideas. Chadwick kept the problem in the back of his mind while working on other things.

Seated at the head of the periodic table, hydrogen is the lightest element, a minimalist atom consisting only of a proton and an electron. It is not scarce: three-quarters of the mass of the ...

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. This attraction holds the atom together. It is ...
