Nitrogen's Atomic Number is 7, which means it has 7 protons and 7 electrons. An atom which is electrically balanced has the same number of protons & electrons. Nitrogen has â¦ an Atomic Mass of 14.00.Most of the mass of an atom comes from the protons and neutrons, so {# protons} + {# neutrons} = Atomic Mass 7 + {# neutrons} = 14, so # neutrons = 7.f it is an isotope of nitrog â¦ en other than the  most common (N-14), the number of neutrons will be different.   Protons = Atomic Number   Neutrons = Atomic Mass-Protons   Electrons = Protons   Atomic number is the amount of protons in element.
