Apr 22, 2006 The protons and neutrons in an atomic nucleus, on the other hand, are absorbs a neutron, it will transmute from thorium-232 to thorium-233.
The half-life of 233 Th is approximately 21.8 minutes . The resonance integral of thorium is one third that of 238 U and fewer neutrons are absorbed in 232 Th. Another factor is the loss of neutrons by absorption in the intermediate nuclide 233 Pa in the reaction chain of 232 Th to 233 U, which is much higher than in the corresponding intermediate nuclide 239 Np in the reaction chain of 238 U to 239 Pu. When a nucleus of thorium-232 absorbs, or “captures,” a neutron, it becomes thorium-233, whose half-life is approximately 21.83 minutes. After that time the nuclide decays through electron emission to protactinium-233, whose half-life is 26.967 days. The protactinium-233 nuclide in turn decays through electron emission to yield uranium-233. How many protons in thorium-232.
