Question

Determine the identity of the daughter nuclide from the alpha decay of  Po.

Quizplus · Accepted Answer

Alpha decay results in the emission of an alpha particle, which is a helium nucleus consisting of two protons and two neutrons. In this question, the parent nuclide is 211Po, which has an atomic number of 84. When it undergoes alpha decay, it emits an alpha particle, reducing its atomic number by 2 and its atomic mass by 4. Therefore, the daughter nuclide will have an atomic number of 82 and an atomic mass of 207. From the provided choices, only option D (11ea888e_e2fd_0e51_a96f_895002fdb7c4_TB6107_11 Pb) has these properties, making it the correct choice.
