Isotopes and Atomic Notation

A short video that explains what isotopes are and how scientists use atomic notation to express which atoms they're talking about. Worksheet included.
This video is a small excerpt from Shedding Light on Nuclear Radiation Episode 1: Atomic Structure.
The Shedding Light on Nuclear Radiation series makes it easy to learn all the essentials of nuclear radiation, including
• atomic structure, isotopes, and nuclides;
• what alpha, beta, and gamma radiation are and how we have learned to harness their power and;
• the concept of half-life.
