Hi folks - Here is the Friday Element Quiz Answer:

The Question:

This element has a FCC crystal structure and is the second most ductile 
metal. The liquid form of this element can dissolve atmospheric oxygen. 
Over 700,000 kg of this element is used in catalytic oxidation reactions 
on a global scale. This element is the by-product of Pb, Zn, Cu and Au 
mining processes. What element is being described?

The Answer:

The element is Silver (Ag). Silver has some unique characteristics that 
make it an important material for industry. The optical reflectivity of 
polished silver is 95% for visible light and 98% for infrared light. 
Silver has the highest electrical conductivity of any material at 20C and 
its thermal conductivity is the highest of all the metals. Silver oxide is 
as conductive as metallic silver making it a key contact material in many 
applications. Only gold is more ductile than silver - a 20 kg ingot of 
silver can be drawn into a wire long enough to encircle the Earth. Silver 
also played a role in the evolution of the dollar. Spain began minting 
coinage (pieces of eight - reales) from the huge silver deposits 
discovered in Mexico. The silver coins dominated maritime trading and 
became known as Spanish dollars. One of the designs contained two 
architectural columns representing the pillars of Hercules at Gibraltar. 
The pillars were wreathed in an S-shaped swirl of ribbon bearing a Latin 
description. The abbreviation for the dollar became two vertical pillars 
superimposed on the S-shape of the ribbon which we continue to use today - 
$.

Many correct answers but David Bealer of Watchfire Signs was first. Clumpy 
will have to pack his cot onto his John Deere mower, leave Bev's lab and 
head to David's shop for his next assignment.
