The charge number of an atomic nucleus is the chemical element's atomic number, also known as nuclear charge number (symbol Z). This is equivalent to the proton number (np), or the number of protons present in the nucleus of each atom of that element, for conventional nuclei. Ordinary chemical elements can be uniquely identified by their atomic number. The atomic number and the number of electrons are both equal in a regular, uncharged atom.
