Nuclear Decay Processes: Alpha, Beta, and Gamma Radiation Explained

The video tutorial covers nuclear equations for alpha, beta, and gamma radiation. It explains alpha decay using uranium-238 and radium-226, highlighting the loss of protons and neutrons. Beta decay is discussed with carbon-14, focusing on neutron-to-proton conversion and electron emission. Gamma radiation is described as pure energy with no mass or charge, using thorium-234 as an example. Neutron emission is illustrated with beryllium-9, emphasizing the loss of a neutron. The tutorial aims to clarify these processes and their effects on atomic structure.
