203), which showed that the intensity ratio of isotopic bands does not always give directly the relative abundance of the isotopes. The following is an account of the determination of the ...

Chlorine naturally exists as two isotopes, \(_{17 ... and 25 atoms have a mass number of 37. To calculate the relative atomic mass, A r, of chlorine: \(A_{r} = \frac{total~mass~of~atoms}{ ...

This variation in the relative abundance of stable isotopes results from tiny mass differences that cause the isotopes to act differently in chemical reactions and physical processes. The lighter ...
