Question 35

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

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

$6α6\alpha$ and $4β−4\beta^-$

$6α6\alpha$ and $8β−8\beta^-$

$8α8\alpha$ and $8β−8\beta^-$

$4α4\alpha$ and $4β−4\beta^-$
