Question

The nuclide  Tl is the daughter nuclide resulting from the $\alpha$ decay of what parent nuclide?

Quizplus · Accepted Answer

The given nuclide is 11eaa8f0_66cb_c882_93a6_89dbed13e561_TB6423_11 Tl. It is a daughter nuclide resulting from a decay process. The decay process is given as F1F1F1S1F1F1F10. This indicates that an alpha particle (α) is emitted during the decay, with the resulting nucleus having atomic number two less than the parent nucleus. The parent nucleus must thus have an atomic number of 83 (81+2). Among the given options, only Bi (atomic number 83) satisfies this constraint and is thus the parent nucleus. Therefore, the correct answer is D.
