The radioactive isotope 247Bk decays by a series of or-particle and β-particle productions, taking 247Bk through many transformations to end up as 207Pb. In the complete decay series, how many a particles and β particles are produced?
Answer to relevant QuestionsThere are four stable isotopes of iron with mass numbers 54, 56, 57, and 58. There are also two radioactive isotopes: iron-53 and iron-59. Predict modes of decay for these two isotopes, and write a nuclear reaction for each. Krypton consists of several radioactive isotopes, some of which are listed in the following table. Isotope ....
