How did chadwicks work lead to isotopes
Web1 de jan. de 2016 · Lead is unusual in that it has a wide range of natural isotopic variation, due to the fact that three of its four stable isotopes ( 206 Pb, 207 Pb, and 208 Pb) lie at the end of major radioactive decay chains. The chains with their half-life are as follows: 238 U → 206 Pb T ½ = 4.468 × 10 9 years. 235 U → 207 Pb T ½ = 0.7038 × 10 9 years.
