Take a look at this periodic table. It shows the nationalities of the discoverers of the various elements. First find out when a section was discovered and then come up with reasons why you these countries made these discoveries and not other countries around the world. In other words, from the standpoint of what was historically happening at the time, why did these countries make these discoveries. It might be best if you just looked at a single group.

Not quite what I am asking here, but tell me more about this iron experiment.

rubidium was found by gustavkirchhoff while looking at the bright red lines of the emission spectrum.

I need more. This doesn't really address the question completely. Interesting though.

Group 2A contains the discoveries of the United Kingdom and France. France discovered Beryllium in 1797, and Radium in 1898. The United Kingdom discovered Magnesium (1755), Calcium (1808), Strontium (1790), and Barium (1808). At the time that France discovered Beryllium, they were at war. I think that they may have discovered this element at this time because Beryllium is used in in spark-proof tools and nuclear reactions. These are both things that could be useful during the war. In the United Kingdom in 1755, there was an extreme tsunami. This could have something to do with the discovery of magnesium because this element is found in salt water. It is possible that Strontium led to the discovery of calcium in the United Kingdom because strontium turns to calcium in the human body.

Great hypothesizing! What does everyone else think? Maybe someone can do more than just speculate and do some research? ...As to the nuclear reactions that didn't happen until in mid 20th century.

Juan José and Fausto Elhuyar, discovered Tungsten in 1783 in samples of the mineral wolframite. Tungsten used to be known as wolfram. The de Elhuyar brothers found an acid in wolframite in 1783 that they succeeded in reducing to the elemental metal with charcoal.

Good job Knobloch, but what was happening in the country at this time? Most people seem to gloss over this part.

The element Titanium was first named Gregorite and discovered by a British chemist named Reverend William Gregor in 1791. Reverend decided to name this element after the Titans of Greek mythology. Titanium is also in the group of metals. Titanium was discovered In Cornwall, Great Britain and he found black sand by a stream by the parish of manaccan and found out that the sand was attracted to magnets.

Another nice posting about discovery, but doesn't answer the whole question once again! Help me someone!

Ohhh! people aren't saying what was happening in the time period. Pierre Janssen was a French astronomer who discovered helium in 1868. He was observing a solar eclipse in India when he noticed the yellow spectral emission lines of the element. An English astronomer by the name of Norman Lockyer observed the same spectra and proposed the name helium after the Greek name for the sun, Helios. and as for what was going on in 1868 published a book called The Variation of Animals and Plants under Domestication. A french geologist discovers Cro-magnen skeleton in Les Eyzies, Dordogne, France. Also Thomas Edison invented the voting machine

Oops i meant to put Charles Darwin published that book. :P

Chromium (Cr 24) was discovered by Louis-Nicholas Vauquelin (a french man) in the mid 18th century (1797). A French man discovered this because, oh I don't know . . .it is an natural ore IN FRANCE. Comments are closed.
