2.39 The mass number is given by: A = Z + N, where Z is the number of protons and N is the number of neutrons. From the periodic table we find that nitrogen’s atomic number is 7 so there are 7 protons. Since the mass number is 13, the number of neutrons is Z = A – N = 13 – 7 = 6.

Feb 03, 2016 · As a result, you can determine the number of protons an element has from the atomic symbol if you have a periodic table handy. The atomic mass is also different for every element, and also for isotopes of the same element. The atomic mass is equal to the number of protons that an element has plus the number of neutrons that an element has.
