How did chadwicks work lead to isotopes
WebJ.R. Encinar, M. Moldovan, in Encyclopedia of Analytical Science (Second Edition), 2005 Isotope Ratio Measurements. Lead isotope ratios can provide analytical information about sources of lead contamination whereas lead concentration measurements cannot. Due to this fact, studies of the isotopic composition of lead are commonly used in environmental … WebLead (82 Pb) has four stable isotopes: 204 Pb, 206 Pb, 207 Pb, 208 Pb. Lead-204 is entirely a primordial nuclide and is not a radiogenic nuclide.The three isotopes lead-206, lead-207, and lead-208 represent the ends of three decay chains: the uranium series (or radium series), the actinium series, and the thorium series, respectively; a fourth decay …
