Particle Physics and Decay Processes

This video tutorial covers the basics of radioactive decay, a key concept in nuclear chemistry. It explains different types of particles involved in decay processes, including alpha, beta, positron, proton, neutron, and gamma particles. The video provides examples of beta decay, positron production, electron capture, and alpha particle production, illustrating how these processes affect atomic numbers and mass. The tutorial emphasizes the importance of balancing equations in nuclear reactions and highlights the transformation of particles within the nucleus.
