There are 22 neutrons in one atom of argon. On the periodic table, argon's atomic number is 18. This tells you that it has 18 protons. To find the... Learn more about this topic: Argon | Definition, Properties & Uses from Chapter 28/ Lesson 17 ...
In chemistry, the indication of the total number of protons present in the nucleus of one atom of a chemical element is usually done by their atomic number. The position of the chemical element in the periodic table is also represented by its atomic number...

Determine the number of electrons using the atomic number. An atom has a neutral charge, so the positive and negative charges are equal to each other. The atomic number is also the number of electrons. Step 3 Calculate the number of neutrons by taking the mass number and subtracting the nu...
It's not that simple though. An atom's properties can change considerably based on how many of each particle it has. If you change the number of protons, you wind up with a different element altogether. If you alter the number of neutrons in an atom, you wind up with an isotope. For...
