How many neutrons, protons, and electrons are in each of these five isotopes? Isotope Neutrons Protons Electrons 238U 234U 214Pb N … 2021-4-11 · While the first only has one fast decay in the sub-chain (234Pa->234U), the second has two consecutive beta decays with comparable lifetimes (27' and 20'). The third also gives two beta electrons. In total, every 238U decay eventually produces 5 beta electrons, randomly distributed with a complex function of the listed lifetimes. See the answer.

A stainless steel chamber capable of holding up to 10 sample-detector modules was used to house the samples and detectors and was filled with a circulating Ar:CO 2 (85:15) mixture at atmospheric pressure.

The origin of the fast decay is supposed to be aemission from the neutral 234U and 238U atoms evaporated from the metallic uranium target.
