What are the numbers of the subatomic particles in nitrogen?
There are 21 basic subatomic particles (neutrons, protons, electrons)
As each of these basic particles can break down into even smaller pieces the exact number of smallest pieces is presently unknown.
The most common isotope of Nitrogen is
This isotope has 7 protons 7 neutrons and 7 electrons, for a total of 21 basic subatomic particles.
Other isotopes that would be radioactive and unstable would have a greater or lesser number of neutrons changing the total number of basic particles.
