proton
Nucleus's positive resident
A proton is a subatomic particle with a positive electric charge, found in the nucleus of every atom.
The number of protons determines which element an atom is—hydrogen has one, helium has two, uranium has ninety-two.
Protons and neutrons make up atomic nuclei, while electrons orbit around them.
