The total energy liberated during the fission of a uranium nucleus amounts to__________________?

Select your answer for: The total energy liberated during the fission of a uranium nucleus amounts to__________________?
Show answer

Answer: C. 199 MeV

Explanation

The fission of a single uranium-235 nucleus releases approximately two hundred million electron volts of total energy. Detailed nuclear physics measurements place this exact energy release value very close to one hundred ninety-nine megaelectronvolts. Mass defect calculations convert a fraction of the heavy nucleus mass directly into kinetic energy during splitting. Megaelectronvolts serve as the standard unit of energy measurement in subatomic particle physics and nuclear reactions. When a thermal neutron splits uranium-235, fission fragments, gamma rays, and prompt neutrons carry away the energy. Einstein mass-energy equivalence equations explain the exact amount of energy liberated during nuclear fission events.

Five megaelectronvolts vastly underestimates the total thermal and kinetic energy released by uranium nucleus fission. Ten megaelectronvolts is much lower than the actual energy yield produced during a standard uranium-235 fission event. Other values such as one hundred sixty-eight or eleven megaelectronvolts contradict established nuclear physics data.
