Guess the Element! - WINNER DECLARED!

[rheavon]

The winner is.... margiejohnson! She answered correctly with the element, Bismuth!

Thanks all for playing!!!

----------------

Ahoy chemists!

I have a periodic table on my desk at work. I closed my eyes and randomly pointed to an element. Your mission, should you choose to accept it, is to guess that element.

The winner will receive a 15/15 insert/non-insert coupon envie. So 30Qs overall!

Now, you could just guess the element- but if you also provide me with the Atomic Mass, I will throw in 5 extra non-inserts. (So 35 Qs total if you get it!).

One guess per person per day until someone gets it.





Clues (will appear once a day - however, you might scan the rest of this thread for clues.....)

• You will not find this element in pure water.
• This element has been used in the medical field.
• This element is not actively mined in Africa.
• This element is classified as a "poor metal."

Good Guesses (Thru post #36)

4: Be - Beryllium (9.01 amu)
Can be found in the mirrors in some telescopes and is a material used in the creation of semiconductors.

5: B - Boron (10.81 amu)
Often used to make labratory and bakeware glassware due to its high heat resistance.

8: O - Oxygen (16.00 amu)
The element which makes up 1/3 of pure water. Fire cannot be present without it.

9: F - Fluorine (19.00 amu)
The element which helps prevent tooth decay.

10: Ne - Neon (20.18 amu)
Despite the name of neon signs, Ne is used along with other noble gases to create different colors in neon signs. Ne is usually reddish-orange.

11: Na - Sodium (22.99 amu)
Mainly found naturally in compounds, such as salt (NaCl). Pure Na is highly reactive.

12: Mg - Magnesium (24.31 amu)
Found in Spinach and also helps contribute to the production of cast iron.

13: Al - Aluminum (26.98 amu)
Your street light poles may be made from this.

15: P - Phosphorus (30.97 amu)
You can find this element in the heads of strike-anywhere matches.

18: Ar - Argon (39.95 amu)
Used in thermal insulation in energy efficient windows.

19: K - Potassium (39.09 amu)
A typical component of fertilizer. Bananas have lots of it!

20: Ca - Calcium (40.08 amu)
Used to make cement and cheese.

22: Ti - Titanium (47.97 amu)
Used to make divers knives and submarines due to water corrosion resistance.

24: Cr - Chromium (52.00 amu)
An element often used in leather tanning.

26: Fe - Iron (55.85 amu)
While it is the most abundant element on the planet, most of it is located beneath the earth's crust.

27: Co - Cobalt (58.93 amu)
If you come across old, blue glass- it is most likely made with cobalt.

29: Cu - Copper (63.55 amu)
The Statue of Liberty is made of copper.. so why is it green? The green is the patina or the green discoloration caused by moisture, oxygen, and other environmental factors.

30: Zn - Zinc (65.38 amu)
Commonly used as a galvanizing agent, coating steel or iron to prevent corrosion.

33: As - Arsenic (74.92 amu)
It used to be in optical glass, but is no longer permitted.

47: Ag - Silver (107.87 amu)
I learned the hard way that while silver is pretty to look at, in the lab elemental silver can stain your skin and clothing brown. This is not the case for silver jewelry, dining accessories, etc because those are not pure elemental silver.

52: Te - Tellurium (127.60 amu)
One of the rarest, solid stable elements occuring on the Earth - you often see it attached to something, hardly by itself.

53: I - Iodine (126.90 amu)
Those pens at the checkout to see if your money is real? Yep. They probably have iodine in them.

55: Cs - Cesium (132.91 amu)
Used in the atomic clock. Also most likely used to keep track of time for your cell phone.

56: Ba - Barium (137.33 amu)
Used to help x-ray digestive system abnormalities through a "barium meal" as the element is opaque on an x-ray photograph.

66: Dy - Dysprosium (162.50 amu)
Used in the production of lasers.

74: W - Tungsten (183.84 amu)
Used as an alternative to gold or plantinum in jewelry making.

79: Au - Gold (196.97 amu)
Used in jewelry, it is also one of the softest of metals.

80: Hg - Mercury (200.59 amu)
It was said that the Mad Hatter in Alice in Wonderland suffered from Mercury Poisoning. This was because mercury was used to cure the felt of hats and hatmakers often inhaled the toxic substance and ultimately perished as a result of mercury poisoning.

81: Tl - Thallium (204.38 amu)
Once used as a rat poison and ant killer. Toxic!

82: Pb - Lead (207.20 amu)
Romans used lead pipes for their plumbing system. Fortunately, now we know that lead + human consumption = lead poisoning. If you live in an older home, don't forget to have your paint tested for lead.

86: Rn - Radon (222 amu)
Over-exposure to radon may cause respiratory disease and cancer, however in some cases it does prove beneficial as a treatment against cancer cells. However, it is uncommon to treat cancer with radon due to the fact there are many other elements and molecules which are slightly less dangerous and just as effective.

93: Np - Neptunium (237.0 amu)
A by-product of nuclear reactors and plutonium production.

I am NOT a chemist - but I have stayed in a Holiday Inn Express so I'm gonna guess Magnesium - 24.3050.

Thanks for the chance!!
