Hope this will help trap bed bugs in the future.
I personally find that the controversies of columbium (Cb) / niobium (Nb) and tungsten / wolfram and related stories are pretty interesting. Here is a “short” version of what happened based on Wikipedia:
In 1802, tantalum (Ta) was discovered by the Swedish chemist Anders Ekeberg. The name comes from Tantalus, a Greek mythological figure. Tantalus is most famous for his eternal punishment in Tartarus. He was made to stand in a pool of water beneath a fruit tree with low branches, with the fruit ever eluding his grasp, and the water always receding before he could take a drink. This is the origin of the English verb tantalize. Ekeberg wrote “This metal I call tantalum … partly in allusion to its incapacity, when immersed in acid, to absorb any and be saturated.”
In 1801, columbium (Cb) was discovered by the English chemist Charles Hatchett from a mineral sample that had been sent to England from Massachusetts, United States. The new element was named as columbium after Columbia, the poetical name for the United States.
However, due to similar properties of Cb and Ta, some people thought that Cb is identical to Ta. In 1846, the German chemist Heinrich Rose argued that there were two different elements in the tantalite (tantalum oxide) sample, and named them after children of Tantalus: niobium (from Niobe), and pelopium (from Pelops). This confusion arose from the minimal observed differences between tantalum and niobium. The claimed new elements pelopium, ilmenium and dianium were in fact identical to niobium or mixtures of niobium and tantalum.
Cb was used in America, while Nb was used in Europe. In 1949, IUPAC chose niobium (Nb) as the official name of this element. The compromise was that IUPAC accepted tungsten instead of wolfram, in deference to North American usage, for element 74.
The name “tungsten” (from the Swedish tungsten, “heavy stone”) is used in English, French, and many other languages as the name of the element, but not in the Nordic countries. The other name “wolfram” (or “volfram”), is used in most European (especially Germanic and Slavic) languages, and is derived from the mineral wolframite, which is the origin of its chemical symbol, W. (Compromise again. Today if you say Wolfram, most people would think about Wolfram Alpha, I guess.)

Po instead of K for Potassium, So instead of Na for Sodium, Tu/Tn instead of W for Tungsten seem so straightforward! Nitrogen used to be called Azote? No wonder RN2+ is called diazonium!
1. Ag Silver
Ag is from Latin name Argentum.
2. Au Gold
Au is from Latin Aurum, which means “shining dawn”.
3. Cu Copper
Cu is from Latin Cuprum, which means Cyprus.
4. Fe Iron
Fe is from Latin ferrum, meaning “iron”.
5. Hg Mercury
Named after Mercury, the god of speed and messenger of the Gods, as was the “planet Mercury” named after the god. The symbol Hg is from Greek name, ὕδωρ and ἀργυρός (hydor and argyros), which became Latin, Hydrargyrum; both mean “water-silver”, because it is a liquid like water (at room temperature), and has silvery metallic sheen.
6. K Potassium
K is from Latin name, Kalium.
7. Na Sodium
From the English, “soda”, used in names for Sodium compounds such as caustic soda, soda ash, and baking soda. The symbol Na is from Modern Latin noun natrium.
8. Pb Lead
Pb is from Latin name, Plumbum, hence the English, “plumbing”.
9. Sb Antimony
Sb is from Latin name Stibium.
10. Sn Tin
Sn is from its Latin name Stannum.
11. W Tungsten

Perhaps for most people, the first thing they think about chemistry is the periodic table of elements. I found that Element FAQs at about.com and Wikipedia are both great sources for interesting facts/lists about elements. Some of my favorite are:

I realized how great the earlier chemists are. Here you see big names like Scheele, Davy, Berzelius.

For sure Mendeleev is on this list.

This reminds me of a classic joke for nerds (find more here):
Einstein, Newton and Pascal are playing hide and go seek. lt’s Einstein’s turn to count so he covers his eyes and starts counting to ten. Pascal runs off and hides. Newton draws a one meter by one meter square on the ground in front of Einstein then stands in the middle of it. Einstein reaches ten and uncovers his eyes. He sees Newton immediately and exclaims “Newton! I found you! You’re it!”
Newton smiles and says “You didn’t find me, you found a Newton over a square meter. You found Pascal!”

What Is the Most Expensive Element?
Since personally I am doing palladium chemistry, I googled the price for Pd and Ni. On 12/20/2014, Pd is about $800/oz, and Ni is about $7/lb. i.e. Pd is more than 1800 times as expensive as Ni. However, in academia, researchers tend to use Pd, usually because it gives better results. but I doubt that Pd is always 1800 times better than Ni. I remember once a speaker said: “Do not use cheap metals. They give cheap results.”
