Exploring Types of Nuclear Decay

The video explores atomic stability, focusing on nuclear decay processes like alpha, beta, and gamma decay. It explains how these processes affect atomic structure and stability, using examples to illustrate the changes in atomic mass and number. The video also touches on positron emission and its role in nuclear reactions.
