The total proton charge means the charge of proton multiply by the total number of protons. As we know a charge on proton in Coulombs is,
Charge on Proton  =  1.602 × 10⁻¹⁹ C
Now, number of protons from total proton charge is calculated as,
              As Total proton Charge =  1.602 × 10⁻¹⁹ C × # of Protons
Or,
                # of Protons  =  Total Proton Charge ÷ 1.602 × 10⁻¹⁹ C
Putting Values,
                   # of Protons  = 1.12 × 10⁻¹⁸ C ÷ 1.602 × 10⁻¹⁹ C
                 # of Protons  =  6.99 ≈ 7
Result:
          Total Number of Protons are 7, so The element is Nitrogen as Number of Protons show Atomic Number and Atomic Number of Nitrogen is 7.
