The proton is, in effect, the index particle of any atom. It is the number of protons in an atom that determines the identity of the element an atom belongs to; in other words, if two atoms have a different number of protons, they are not the same element. A proton is a subatomic particle with a positive electrical charge found within the atomic nucleus of atoms . The number of this sub-particle in the atomic nucleus determines the atomic number. The chemical elements are ranked in the periodic table of the elements accordingly to the atomic number. A proton is a component of an atomic nucleus with a mass defined as 1 and a charge of +1. A proton is indicated by either the symbol p or p +. The atomic number of an element is the number of protons an atom of that element contains. Because both protons and neutrons are found in the atomic nucleus, they are collectively known as nucleons. CvxFKIs.
