It was a French discovery and was named after France. In nature, it is found in tiny quantities in Uranium which was discovered by a German. It is estimated that no more than 30g of Francium exists on Earth at any time.

Re: Chemical elements
Yes, liked that. Not sure about coiffured though. His hair reminded me a tad of that unkempt, escaped sheep that lived like a hermit up a New Zealand hill for ages. C.Clitheroekid wrote:Indeed - and a fascinating history, as related by an elegantly coiffured professor...

Anyone know any jokes about Sodium.
Would a Clerihew do?
“Sir Humphrey Davy
Abominated gravy.
He lived in the odium
Of having discovered sodium. “

Re: Chemical elements
Jokes about [expletive deleted] will undoubtedly receive the high level of moderation they deserve.

On a more serous note (which many of the infantile minds on here will find snigger-worthy), there is a compound, also known as [expletive deleted] or arsacyclopentadiene, which has the preferred IUPAC name of "arsole". Note that there is no "e" between the "r" and the "s"; this is a perfectly clean word which mature minds find neither offensive nor in any way humourous ( ).

Re: Chemical elements
As would be expected an arsole consists of a single ring of atoms. C.jfgw wrote:On a more serous note....

The chemical term, "aromatic" is used to refer to a ring-shaped molecule that is flat. Arsole is not entirely flat and its aromaticity is debated,
Aromaticity of the arsole manifests itself in delocalization and resonance of its ring electrons. It is closely related to planarity in that the more planar the molecule the stronger its aromaticity.[10] Aromaticity of arsole and its derivatives has been debated for years both from experimental and theoretical point of view. A 2005 review combined with quantum chemical calculations concluded that arsole itself is "moderately" aromatic as its ring current is 40% that of pyrrole, which is known to be aromatic. However, comparable ring current was calculated for cyclopentadiene, which has long been regarded as non-aromatic.[2] Other reports suggest that the aromaticity (and planarity) can vary between arsole derivatives.[9]
