• Proton Definition. 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.

• PROTONS: The particle has a positive electrical charge, equal and opposite to that of the electron. If isolated, a single proton would have a mass of only 1.673 × 10-27 kilogram, just slightly less than the mass of a neutron. The number of protons in an element's nucleus is called the atomic number.

• Protons have a much smaller mass than neutrons. Protons have a much larger volume than neutrons. Protons have an electrical charge, but neutrons have no charge. Protons make up the nucleus, but neutrons orbit around the nucleus. to add a comment.

By convention, a proton's charge is positive and an electron's charge is negative. This is purely arbitrary and has no physical basis. ... An object is electrically charged if it has a net charge, meaning it carries an excess of positive or negative charge.
