Protons are subatomic particles that, along with neutrons, comprise the nucleus or central portion of an atom. The rest of the atom consists of electrons that orbit the nucleus, much as Earth orbits the sun. Protons can also exist outside an atom, in the atmosphere or in space. ...
well, unfortunately not. science has known for a long time that atoms mainly consist of empty space with electrons spinning around a central nucleus of protons and neutrons. and science has known for somewhat less time that these particles, which were once thought to be fundamental, are ...
Virtually all the mass of an atom resides in its nucleus, according toChemistry LibreTexts. The protons and neutrons that make up the nucleus are approximately the same mass (the proton is slightly less) and have the same angular momentum, or spin. ...
Generally, mass is defined as the measure of how much matter an object or body contains - the total number of sub-atomic particles (electrons, protons and neutrons) in the object. If you multiply your mass by the pull of earth's gravity, you get your weight. So if your body weight is...
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on
