Conservation of Nucleon Number

Mr. Andersen explains the conservation of nucleon number and charge in nuclear reactions and radioactive decay. He covers fission, where a nucleus splits, and fusion, where nuclei combine, ensuring nucleon and charge conservation. The video also discusses radioactive decay types: alpha, beta, and gamma, highlighting their properties and conservation principles.
