What Makes an Element Reactive?

In this video excerpt from NOVA: "Hunting the Elements," New York Times technology columnist David Pogue examines how atomic structure determines reactivity. Meet Theo Gray, chemist and author, who helps David explore how the electron configuration of an atom affects its ability to combine with other atoms. Discover why noble gases are not reactive and why halogens and alkali metals are highly reactive.

This video is available in both English and Spanish audio, along with corresponding closed captions.
