Some years ago at the University of North Carolina at Chapel Hill, I taught a one-semester inorganic course for BS chemistry majors. During the class we covered all the noncarbon elements in a ...

BROMINE was discovered by French chemist Antoine-Jérôme Balard and is an element that can be found on the periodic table. The chemical is known as a naturally occurring element, and when handled ...

Early periodic tables were incomplete, since many elements were unknown. Also, some elements were placed in groups with elements that were not similar to them. Mendeleev left gaps in his table for ...

It is an icon of natural science and hangs in most chemistry classrooms: the periodic table of elements, which is celebrating its 150th birthday this year. The tabular overview is closely linked to ...

The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance ...

Many chemical elements behave quite differently depending on the compound they are found in, but Matt Rattley argues that bromine does so in a particularly striking manner. Every element is a little ...
