Question 12

A nucleus of thorium-232 (90232Th^{232}_{90}\text{Th}90232​Th) undergoes a series of radioactive decays to form a stable nucleus of lead-208 (82208Pb^{208}_{82}\text{Pb}82208​Pb).

How many α \alpha\,α particles and β−\beta^-β− particles are emitted during this decay series?

A

6α6\alpha6α and 4β−4\beta^-4β−

B

6α6\alpha6α and 8β−8\beta^-8β−

C

8α8\alpha8α and 8β−8\beta^-8β−

D

4α4\alpha4α and 4β−4\beta^-4β−
