Twin: Nuclear Fission
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Nuclear fission splits a large nucleus into smaller, more stable fragments, releasing energy since those fragments sit higher on the binding-energy curve.
Show
A uranium-235 nucleus absorbing a neutron splits into fragments like barium and krypton, plus neutrons and energy.
Watch for
Fission is favorable only for nuclei heavier than the curve's peak near mass 56 — logic reverses for light nuclei, hence its twin.
