Question 6
Which of the following is a transuranic element that is most likely to have been produced in a nuclear reactor? A. Co-60 B. Np-239 C. U-238 D. Hs-265
Worked Solution & Example Answer:Which of the following is a transuranic element that is most likely to have been produced in a nuclear reactor? A - HSC - SSCE Chemistry - Question 6 - 2017 - Paper 1
Step 1
B. Np-239
Answer
Np-239 (Neptunium-239) is a transuranic element, which means it has an atomic number greater than uranium (92) and is a man-made isotope. It is produced in nuclear reactors through the capture of neutrons by Uranium-238 (U-238) and subsequent beta decay. The other options (Co-60, U-238, Hs-265) are either not transuranic or are not primarily produced in nuclear reactors.
