What is the charge of a neutron? For a neutral atom, the number of protons and the number of electrons are equal. That is, neutron number (n) = atomic mass number (A) atomic number (Z). Moreover, since these two subatomic particles, electrons and protons, have opposite charges, they cancel out and keep the atom neutral. The number of electrons can also be different in atoms of the same element, thus producing ions (charged atoms). And from here, we know that the element has 13 protons because the number of protons is equal to the number of electrons in a neutral atom.
