The relation between chemical atomic weight and atomic number== Inasmuch as it is now recognised to be in general merely a statistical mean value the importance of the chemical atomic weight has been greatly reduced by the discovery of isotopes. Its position as the natural numerical constant associated with an element has been taken by the atomic number, though from the point of view of chemical analysis the chemical..."
