Isotopes and Radioactivity
Lecture no. 27 from the course: The Joy of Science
Taught by Professor Robert M. Hazen | 29 min | Categories: The Great Courses Plus Online Science Course
The discovery of radioactivity, and the subsequent exploration of the atomic nucleus, led to nuclear physics and nuclear chemistry. About one atom in a million is radioactive. Such atoms can decay through alpha, beta, or gamma radiation, all of which are dangerous because they can disrupt chemical bonds.
