A radioactive nucleus of uranium-238 (92238U^{238}_{92}\text{U}92238U) decays via a series of alpha (α\alphaα) and beta-minus (β−\beta^-β−) emissions to form a stable lead-206 (82206Pb^{206}_{82}\text{Pb}82206Pb) nucleus.
What is the total number of neutrons lost by the nucleus during this decay chain?
