Question

Quizplus · Accepted Answer

Excess electrons are not needed for a nuclear chain reaction. Nuclear chain reactions are driven by the interaction of neutrons with fissionable material, requiring a critical mass and often neutron moderators to sustain the reaction, but they do not involve the role of electrons in their fundamental process.
