La fisión nuclear

The video discusses how energy can be obtained from atomic nuclei through nuclear fission, a process that splits the atomic nucleus to release energy. It explains the efficiency of fission with heavy element isotopes like uranium and describes the controlled and uncontrolled fission processes. Controlled fission is used in nuclear power plants for safe energy production, while uncontrolled fission is the basis for nuclear weapons. The video highlights the potential and dangers of nuclear energy.
