When uranium-238 (Z = 92)is bombarded with a neutron,it can change into
A)uranium-237.
B)uranium-239.
C)protactinium-239 (Z = 91).
D)neptunium-239 (Z = 93).
E)none of the above.

Question

Quizplus · Accepted Answer

When uranium-238 is bombarded with a neutron, it undergoes neutron capture to form uranium-239. This unstable nucleus undergoes beta decay to form neptunium-239, which further undergoes beta decay to form plutonium-239. Therefore, option B, uranium-239, is the correct answer. Options A, C, and D are incorrect as they do not account for the complete decay chain.
