The number of protons in the nucleus of an atom determines the species of the atom, i.e., the element to which the atom belongs. An atom has the same number of protons and neutrons. But the electron number cannot be used instead because  a electrons are not within the nucleus  b electrons are negatively charged  c electrons can be removed from or added to an atom  d electrons are lighter than protons
