Question

As radioactivity uranium decays it turns into what stable element

Answer 1

Answer:

thorium-234

Explanation:

Uranium's most stable isotope, uranium-238, has a half-life of about 4,468,000,000 years. It decays into thorium-234 through alpha decay or decays through spontaneous fission.

Uranium-238 decays by alpha emission into thorium-234, which itself decays by beta emission to protactinium-234, which decays by beta emission to uranium-234, and so on. The various decay products, (sometimes referred to as “progeny” or “daughters”) form a series starting at uranium-238. After several more alpha and beta decays, the series ends with the stable isotope lead-206.
