Rhenium was the lower one and indeed it was the last stable, non-radioactive, naturally-occurring element to be discovered. In 1905, Masataka Ogawa found it in the mineral thorianite from Sri Lanka. He realised from lines in its atomic spectrum that it contained an unknown element. He wrongly thought it was the one directly below manganese and ...

Name: Named after the Rhine River. Originally described as tiny grains in wolframite from a Russian locality (Rafalson & Sorokin, 1976). Later discredited because of uncertain origin. Also observed as microscopic grains (no size given) in calcium- and aluminum-rich inclusions in the Allende Meteorite, a carbonaceous chondrite.

Rhenium foil. These are tiny little strips of rhenium foil about half an inch long. If they were made of aluminum this would be a pile of fluffy shreds. But it's rhenium, one of the hardest and densest elements, so instead it's a surprisingly heavy mass of fairly stiff strips. Source: eBay seller forsythia Contributor: Theodore Gray
