What does the number 40 in argon-40 represent?
It is the mass number, i.e., the total number of protons and neutrons in argon and is ofter used to calculate the number of neutrons present. As the atomic number (or the number of protons) for argon is 18, there will be 22 neutrons in Argon-40 isotope.
In order to calculate the number of neutrons you must subtract the from the?
Number of neutrons = Mass number - atomic number
