Rhenium can't be made in a pot, because it can get really hot, it melts at over 3,000 degrees, that's so hot that nothing can freeze. Rhenium's so dense, that it hardly makes sense, it's as solid as steel, but don't feed it to an eel, 'cause of its radioactive isotope, you have got no hope.

 

 

History

            In 1925 the periodic table was almost complete, however a couple of elements yet to be discovered. Elements 43 and 75 are now called Technetium and Rhenium. As the race began many scientists went in search of discovering either of these elements. After several months a German group of scientists including Walter Noddack (1893-1960), Ida tackle (1896-1979), and Otto Berg (1873-1939), discovered not just one but both of the missing elements. Although before they were official other scientists had to prove them to truly be found by these scientists. Element 43 was not proven to be found, on the other hand element 75 was. These scientists named the element Rhenium after the Latin word for the River Rhine in Germany. Rhenium was the next-to-last naturally occurring element to be discovered and the last element to be discovered having a stable isotope.

Where Found and extraction

Rhenium can be found many places in the world. However the most common places that it is found are Argentina, the United States of America, and Canada, but it can also be found in Germany and Russia. The extraction process is slow and expensive, adding to its already high cost. The process starts with getting large rhenium-molybdenum ores and roasting them at extremely high temperatures until the molybdenum is melted. Next the rhenium is extracted from the molybdenum and cooled until it is a solid again.

Uses

         Since the discovery of, Rhenium has been thought of as an element in superalloys. It is naturally an alloy, usually Molybdenite-Rhenium, Copper-Rhenium, Tungsten-Rhenium, and Columbite-Rhenium alloys, and in all of them it is superconductive. That is one reason that it is used in jet engines and devices such as extreme heaters for temperatures up to 3,000 degrees. Another reason of its strange uses is that it has a melting point of 3453.2 K and a boiling point of 5923 K. Because of these odd properties it is one of the few metals that can withstand temperatures of this proportion. It is also used in Rhenium-Osmium dating, a form of radiometric dating (like carbon dating) to reveal the age of many ores such as gold ores. The Re187 isotope is used in this process along with Osmium, Os188.

Transition Metals

         The Transition Metals, consisting of 40 metals, is by far the largest group on the periodic table. And because of its large size not all of the elements are exactly the same, for example this group consists of gold and silver but also houses mercury. The Transition Metals are all metals though. Rhenium is in a group of metals that consist of Rhenium, Technetium, Manganese, and Bohrium. Manganese is the least reactive, then slightly more reactive is Technetium. Then comes Rhenium, and Bohrium.
