question 12 of 30
what is produced when uranium-235 undergoes fission?

a. two smaller nuclei and neutrons
b. one smaller nucleus and one larger nucleus
c. a larger nucleus
d. diatomic uranium

Explanation:

Nuclear fission is the process where a heavy nucleus (like uranium - 235) splits into two (or more) smaller nuclei, along with the release of a few neutrons and a large amount of energy. Option B is incorrect because fission produces two (or more) smaller nuclei, not one smaller and one larger. Option C is incorrect as fission is about splitting a large nucleus, not forming a larger one. Option D is incorrect because uranium is a metal and does not form diatomic molecules in fission; also, fission is about nuclear splitting, not molecular formation. Option A correctly describes the products of uranium - 235 fission.

Answer:

A. Two smaller nuclei and neutrons
