Fluorine is the most reactive element of all. Most chemists will never use, or even see it. But, there are a few people with more than a few screws loose that will demonstrate how reactive it really ...

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue investigates chemical reactions involving sodium. Find out how the electron configuration of ...

Eric Scerri, a UCLA chemistry lecturer, has written at least six books discussing the orientation of the periodic table. His office is cluttered with posters and three-dimensional models of different ...

The number of electrons in the element's outer shell hugely influences reactivity. If the outer electron shell is full then an additional chemical bond cannot be formed because there is no room. Inert ...

Metals mostly occur as compounds in rocks and minerals and must be extracted before they can be used. The method used to extract the pure metal depends on its position in the reactivity series. Metals ...
