Developing the Periodic Table

In this video excerpt from NOVA: "Hunting the Elements," New York Times technology columnist David Pogue explores how the periodic table of elements took shape. Learn how the periodic table developed its current form when Dmitri Mendeleev organized the elements by families with similar properties as well as by relative weight. In addition, find out how Mendeleev was able to predict elements that had not yet been discovered, and how the periodic table has accommodated dozens of new elements that have since been discovered.

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