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)

What is the atomic number of NH3?
NH3 is a compound, not an element. It does not have an atomic number. If you mean the number of atoms in the molecule the answer is 4: 1 nitrogen and 3 hydrogen. This is not the same as atomic number.
What do you notice about the atomic number and the total number of electrons in an atom of that element?
The atomic number is equal to the number of protons in an atom, which also corresponds to the number of electrons in a neutral atom. This means that the atomic number gives you the total number of electrons in a neutral atom of that element.
