For this reason, the atomic number allows the ordering of the various chemical elements in the periodic table.įinally, any element can always be identified by its number of protons and atomic number.ī. Then it is possible to say that the number of protons in the nucleus, that is to say the atomic number Z, of an atom determines its identity. This number is then responsible for defining the electronic configuration of the atom and the chemical properties of the element. The atomic number (which is identified by the letter Z) indicates the amount of protons that is present in the nucleus of an atom. Thus, the atom is electrically neutral, since the positive charge of the protons is compensated by the negative charge of the electrons.Ītoms of different elements have different amounts of protons.
