en.wikipedia.org › wiki › Atomic_numberAtomic number - Wikipedia The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number (n p) or the number of protons found in the nucleus for every atom of that element. The atomic number can be used to uniquely identify ordinary chemical elements.
