The central portion of atom carrying positive charge is called nucleus.its charges increase regularly as we go down the group like {H+1) (He+2)(Li+3) so this positive charge is called atomic number.an atom is neutral and its nuclear charge is called atomic number which must be equal to number of proton and number of electrons. ITs showing symbol is (Z)
