See the periodic table of elements, e.g. in: So in total, 58 protons, neutrons, and electrons. http://en.wikipedia.org/wiki/Periodic_table#Methods_for_displaying_the_periodic_table Argon has 18 protons and 22 neutrons. well a argons atomic number is 18 that means there are 18 protons&electrons the neutrons are usaly the same.  Argon The number of protons in an atom of an element will always be the same as the atomic number. The atomic number can be found on any periodic table, and in this case, the answer is 18.
