Until 1897, scientists believed that there was no smaller unit of matter in existence than the atom. This changed when J.J. Thomson first discovered the electron, proving the existence of subatomic particles. Later, scientists would also discover protons and neutrons. ...
In the early 1930s it was known that there were protons and neutrons inside the nucleus of the atom. It was also known that protons and neutrons had very similar masses. The mass difference between the proton and the neutron is quite small 鈥 1 part in 700 or so. And the forces ...
The difference between isotopes of an element depends on the number of neutrons. To find the number of neutrons in an isotope, find the mass number of the isotope and the atomic number. The atomic number, or number of protons, is found on the Periodic Table. The atomic mass, also found...

A stable subatomic particle that has a positive electric charge and is part of the nucleus of an atom. Its charge is opposite to that of an electron but is equal in magnitude. A proton's mass is 1,836 times that of an electron. See more atatom. ...
Follow these simple steps to find the number of protons, neutrons, and electrons for an atom of any element.
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 th
The environment within the nucleus of a singleatomseems similar, with protons and neutrons also dancing about. But because the nucleus is such a compact space, scientists have struggled to pin down the behavior of these particles, known as nucleons, in an atom’s nucleu...
