What is a proton?</h3>
The subatomic particle known as a proton has a fixed mass of one and a charge of one (positive charge). Protons are represented by the symbols p or p+. Every atom has protons in its nucleus. The atomic number of an element is determined by how many protons it has.
The atomic nucleus contains both protons and neutrons, which are collectively referred to as nucleons. Protons repel one another due to their positive electrical charge, but when protons and neutrons are sufficiently close to one another, electrostatic attraction is overcome by the strong nuclear force. They can unite because of this. Hadrons include protons and neutrons. Quarks are even smaller subatomic particles that make up a proton. Three quarks make up one proton.
