Conservation of Charge in Reactions

Mr. Anderson explains the conservation of charge in nuclear reactions, focusing on fission, alpha decay, beta minus decay, and beta plus decay. He illustrates how charge and mass are conserved in these processes, using examples like uranium 235 fission, alpha decay of uranium 238, and beta decay of carbon-14 and magnesium 23. The video emphasizes the importance of understanding charge conservation in nuclear reactions, distinct from chemical reactions where electrons play a key role.
