Nuclear Reactions and Decay Types

The video tutorial covers nuclear chemistry, focusing on nuclear reactions and transmutations. It explains the conservation of mass and charge in nuclear reactions, using examples like the fission of uranium, alpha decay of estane, and beta decay of xenon. The tutorial also discusses isotopes, using neon as an example, and highlights the importance of understanding atomic and mass numbers in nuclear transformations.
