Question 40

A radioactive nucleus of uranium-238 ( $92238U^{238}_{92}\text{U}$ ) decays via a series of alpha ( $α\alpha$ ) and beta-minus ( $β−\beta^-$ ) emissions to form a stable lead-206 ( $82206Pb^{206}_{82}\text{Pb}$ ) nucleus.

What is the total number of neutrons lost by the nucleus during this decay chain?

$10$

$16$

$22$

$32$
