Thorium-232 decays by alpha decay. Part of the nuclear equation is shown below. Fill in the blank with a number. 232/90 - 11546309

…isotopes, predominantly the very long-lived thorium-232 (1.40 × 10 10 -year half-life), the parent of the thorium radioactive decay series. Other isotopes occur naturally in the uranium and actinium decay series, and thorium is present in all uranium ores. Thorium-232 is useful in breeder reactors because on capturing slow-moving neutrons

Radioiodines, including iodine-131; Radionuclides, alpha-particle-emitting, 2,3,7,8-Tetrachlorodibenzo-para-dioxin; Thiotepa; Thorium-232 and its decay

the fertile materials uranium-238 and thorium-232, respectively. A fertile material, not itself capable of undergoing fission with low-energy neutrons, is one that decays into fissile material after neutron absorption within a reactor. Thorium-232 and uranium-238 are the only two naturally occurring fertile materials. Thorium-232 undergoes an alpha decay, followed by a B-decay. What is the product nucleus of this two-step decay? Thorium is element 90.
