Question

guided practice
daughter nuclei are produced when a nucleus is struck by ______.
a. a proton
b. a radioactive element
c. a neutron
d. an electron

Explanation:

When a nucleus is struck by a neutron, it can become unstable and undergo nuclear fission, splitting into smaller daughter nuclei along with additional neutrons. Protons or electrons striking a nucleus do not typically produce daughter nuclei in this characteristic fission process, and a radioactive element is a type of nucleus, not a particle that initiates this reaction.

Answer:

C. a neutron
