What would be the daughter nuclide if a Lead-210 isotope underwent alpha decay?

A. Mercury-206
B. Lead-209
C. Lead-210
D. Bismuth-210
E. Thallium-210

Answer :

Final answer:

The daughter nuclide of a Lead-210 isotope undergoing alpha decay is Bismuth-206.

Explanation:

In alpha decay, a Lead-210 isotope would decay into a Bismuth-206 nuclide. This is because during alpha decay, the atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. As a result, the atomic number of the nucleus decreases by 2 and the mass number decreases by 4.
