    www.rsc.org/periodic-table/element/75/rhenium The periodic table had two vacant slots below manganese and finding these missing elements, technetium and rhenium, proved difficult. Rhenium was the lower one and indeed it was the last stable, non-radioactive, naturally-occurring element to be discovered.
  • Rhenium | Definition of Rhenium by Merriam-Webster

    www.merriam-webster.com/dictionary/rhenium Rhenium definition is - a rare heavy metallic element that is obtained either as a gray powder or as a silver-white hard metal, is usually extracted as a by-product of molybdenum smelting, and is used especially in catalysts and alloys.

    pubchem.ncbi.nlm.nih.gov/compound/rhenium Rhenium (Re), the last naturally-occurring element to be discovered, was discovered in Germany in 1925. The process was so complicated and the cost so high that production was discontinued until early 1950 when tungsten-rhenium and molybdenum-rhenium alloys were prepared.
