Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable atom has a net charge of 0. In other words, it has an equal number of protons and ...

He’s a quantum physicist at Washington State University. He told me that protons – along with neutrons – form the nucleus in the middle of an atom. “Atoms make up all the stuff that we see ...

Occasionally, and purely by chance, some of these neutrons collide with the nuclei of some of the nitrogen atoms. The nucleus of each nitrogen atom contains seven protons and seven neutrons.

The strong force holds together quarks, the fundamental particles that make up the protons and neutrons of the atomic nucleus, and further holds together protons and neutrons to form atomic nuclei.

The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

In the cores of neutron stars, the crushing pressures can squeeze apart atomic nuclei, and maybe even protons and neutrons themselves. Neutron stars' surface gravities are so intense that the ...
