What will be the product after the alpha decay of U238?
Correct answer: A. Th234
- A. Th234
- B. Po234
- C. Rn234
- D. None of these
Explanation
Option A is correct since Uranium-238 undergoes alpha decay to become Thorium-234. (The numbers following the chemical names refer to the number of protons plus neutrons.) In this reaction, Uranium-238 loses two protons and two neutrons to become the element Thorium-234.The alpha decay of uranium-238 (U-238) results in the formation of thorium-234 (Th-234) as the product.The decay of U-238 can be represented by the following equation:U-238 → Th-234 + He-4where He-4 is the alpha particle emitted during the decay process.Therefore, the product after alpha decay of U-238 is thorium-234 (Th-234).
