Question

Which isotope is produced in the nuclear reaction: 23892U + 10n → __________ + γ?
Options
A <sup>239</sup><sub>92</sub>U
Correct Answer
B <sup>237</sup><sub>92</sub>U
C <sup>239</sup><sub>93</sub>Np
D <sup>238</sup><sub>92</sub>U
Correct Answer

Option A is the correct answer.

Detailed Explanation

Page 7 shows the reaction '23892U + 10n → 23992U + γ'. The sum of mass numbers on the left is 238 + 1 = 239. The sum of atomic numbers is 92 + 0 = 92. Since a gamma ray (γ) has no mass or charge, the product must be 23992U to conserve both mass and atomic numbers.

Hint

Remember that a neutron adds mass but no charge, and a gamma ray carries energy but no mass or charge.
