Nuclear Stability and Decay Processes

The video explores nuclear stability and the types of nuclear decay processes that can occur. It explains the concept of the belt of stability and how nuclides transition from unstable to stable states. The video covers three main types of nuclear reactions: beta particle emission, positron emission, and electron capture, providing examples and explaining how each process affects the neutron to proton ratio in a nucleus.
