15. 18 is the atomic number for the noble gas argon. 16. Argon and the other noble gases appear in the last column, or group, of the periodic table – group 18. 17.
Number of protons + neutrons = 18 + 22 = 40. Hence mass number = 40The chemical symbol for argon with its mass number and atomic number is: Back to top. Isotopes.
THE position of argon in a classification of the elements depending on atomic weights has been recently defined by C. J. Reed (Journal of the Franklin Institute, July). The elements are assigned ...
