- Proton - Wikipedia
A proton is a stable subatomic particle, symbol p, H +, or 1 H + with a positive electric charge of +1 e (elementary charge) Its mass is slightly less than the mass of a neutron and approximately 1836 times the mass of an electron (the proton-to-electron mass ratio)
- Proton - Simple English Wikipedia, the free encyclopedia
A proton is part of an atom [1] They are found in the nucleus of an atom along with neutrons [1] The periodic table groups atoms according to how many protons they have A single atom of hydrogen (the lightest kind of atom) is made up of an electron moving around a proton
- Proton | Definition, Mass, Charge, Facts | Britannica
proton, one of the three basic subatomic particles—along with neutrons and electrons—that make up atoms, the basic building blocks of all matter and chemistry It is the positively charged particle that, together with the electrically neutral particles called neutrons, make up the nucleus of an atom

A proton is a subatomic particle with a positive charge It resides in the atomic nucleus Atoms consist of smaller particles called protons, neutrons, and electrons Here is the definition of a proton, its electric charge, where it’s found in the atom, and a collection of proton facts Proton Definition

This paper constituted the proton (the primordium, or ‘Anlage,’ if you prefer) of my own subsequent contributions, and likewise, so far as I knew at the time, of the simplified nomenclature in America
- Proton - Scientific Lib
In physics, the proton (Greek πρώτον proton = first) is a subatomic particle with an electric charge of one positive fundamental unit (1 602 × 10−19 coulomb), a diameter of about 1 6 to 1 7×10 −15 m [1], and a mass of 938 27231(28) MeV c 2 (1 6726 × 10 −27 kg), 1 007 276 466 88(13) u or about 1836 times the mass of an electron
- There’s still a lot we don’t know about the proton - Science News
Proton decay would be a sign that three of nature’s forces — weak, strong and electromagnetic — were united early in the universe
- Proton - Energy Education
The charge on a proton is exactly equal and opposite to the charge on an electron Therefore, the number of electrons in a neutral atom is always equal to the number of protons (click here for a Phet simulation about that)
