neutron-induced fission
spontaneous fission
|
What happens to uranium-235 after absorbing a low-energy neutron?
it becomes highly unstable and splits
it remains unchanged
it undergoes nuclear fusion
it becomes highly stable
|
What is the primary reason for the significant energy release during fission reactions?
the overall mass of the daughter nuclei remains the same
the daughter nuclei have a lower binding energy per nucleon
the overall mass of the daughter nuclei increases
the daughter nuclei have a higher binding energy per nucleon
|
What happens to the stability of nuclei as they grow in size?
their stability fluctuates randomly
they become more stable
they become more unstable
their stability remains unchanged
|
What does the instability of large nuclei limit?
the number of neutrons in a nucleus
the number of protons in a nucleus
the number of elements that can exist
the number of isotopes that can exist
|
Which of the following statements about nuclear fission is true?
it does not involve the release of neutrons
it typically results in the formation of larger, less stable nuclei
it typically results in the formation of smaller, more stable nuclei
it only occurs in light nuclei
|
