Half Lives: Quantifying Radioactive Decay Over Time

The video tutorial explains the concept of radioactive decay, emphasizing its random nature and the inability to predict when individual nuclei will decay. It introduces the concept of half-life, which is the time required for half of the radioactive nuclei in a sample to decay. The tutorial provides examples and calculations to illustrate how the number of unstable nuclei decreases over time, using both half-life and percentage decay rates. Graphical representation of decay is also discussed, showing the exponential nature of the process.
