Nuclear Decay: Analyzing Alpha and Beta Processes in Chemistry

Kevin Martin and Joey Smoak present a tutorial on nuclear decay, covering alpha decay, beta decay, and positron emission. They explain the processes using examples like uranium-235 and nitrogen-14, highlighting the changes in atomic and mass numbers. The tutorial emphasizes understanding the loss and gain of particles in the nucleus and relates these changes to the periodic table.
