This resource includes 6 worksheets on materials including isotopes, decay curves, Alpha, Beta & Gamma Decay, Writing nuclear equations and Fission/Fusion reactions. In my experience this works best as a package handed out to students at the start of the Radioactivity portion of your class.
There is a teacher key included.
Although this is designed for an introductory level, students will need to be familiar with basic chemical concepts like atomic number, atomic mass, and writing equations.
Its a great resource to augment your materials or provide different questions on a quiz or summative piece.
