Hi folks - Here is the Friday Element Quiz Answer:

The Question:

This element plays a key role as a constituent of steel. This element is 
an oxidizing agent in processes to make artificial dyes and fragrances. 
The average human takes in about 0.3 milligrams of this element per day. 
This element was not cast as a molten metal until 1959 due to its 
properties. What element is being described?

The Answer:

The element is Molybdenum (Mo)! Mo has a very high melting point so a 
special crucible had to be developed before it could be cast as a molten 
metal. The majority of the time Molybdenum is formed by compressing Mo 
powder at high pressures (HIP processing). A simple test (an oxidation 
process) to identify Mo was developed in 1781 by Karl Scheele which 
resulted in very intense blue solution in the presence of a reducing 
agent. The test has been used for 200 years but no one could figure out 
the physical reaction for the blue color. In 1996 a group of German 
chemists at the University of Bielefeld demonstrated that the blue color 
was the result of a cyclical cluster comprised of 154 Mo atoms interlinked 
with oxygen atoms. Mo was first used by the British in WWI for steel tank 
armor. The addition of Mo made the steel stronger and allowed for reduced 
plate thickness giving the tanks improved agility. This "discovery" had 
actually been made 20 years earlier by the French company Schneider & Co.


The quiz winner this week is Brian Ellis and will get the services of 
Clumpy and Kloumpios again. The guys loaded up their John Deere's and left 
Iowa very early as we have a heat index of 112 for the next few days - 
they figured it would be better in Cyprus.
