WebProtons are positively charged particles found within atomic nuclei. Three quarks make up each proton — two ” up ” quarks (each with a two-thirds positive charge) and one “down” quark (with a one-third negative charge) — and they are held together by other subatomic particles called gluons , which are massless.
