The existence of isotopes was first suggested in 1913 by the radiochemist Frederick Soddy, based on studies of radioactive decay chains that indicated about 40 different species referred to as radioelements (i.e. radioactive elements) between uranium and lead, although the periodic table only allowed for 11 elements between lead and uranium inclusive.

Web6.2.3 Isotopic analysis. Isotopic analysis separates isotopes on the basis of small but significant differences in mass (see Chapter 31 by Lipschultz, this volume). This can be done using an emission spectrometer or a mass spectrometer. With both types of instruments, the sample must be converted to a gas prior to analysis. WebOne of the isotope pairs widely used in geology is the decay of 40 K to 40 Ar (potassium-40 to argon-40). 40 K is a radioactive isotope of potassium that is present in very small amounts in all minerals that have potassium in them.
