History. Rhenium (Latin Rhenus meaning Rhine) [2] was the nexttolast naturally occurring element to be discovered and the last element to be discovered having a stable isotope. [3]The existence of a yet undiscovered element at this position in the periodic table had been predicted by Henry Moseley in 1914. [4] It is generally considered to have been discovered by Walter Noddack, Ida Tacke ...

Rhenium substantially promotes the rate of Ptcatalyzed glycerol hydrogenolysis to propanediols and shifts the product selectivity from 1,2propanediol to a mixture of 1,2 and 1,3propanediols. This work presents experimental evidence for a tandem dehydration–hydrogenation mechanism that occurs over a bifunctional Pt–Re catalyst. Infrared spectroscopy of adsorbed pyridine and the rate of ...

One measure of size is the elementelement distance within the element. It is not always easy to make sensible comparisons between the elements however as some bonds are quite short because of multiple bonding (for instance the O=O distance in O 2 is short because of the the double bond connecting the two atoms. The bond length in ReRe is: ...

Rhenium was discovered by the German chemists Ida TackeNoddack, Walter Noddack and Otto Carl Berg in 1925. They detected rhenium spectroscopically in platinum ores and in the minerals columbite, gadolinite and molybdenite. In 1928, Noddack and Berg were able to extract 1 gram of rhenium from 660 kilograms of molybdenite.
