Hi folks - Here is the Friday Element Quiz Answer:

The Question:

When this element is added to rubber, it speeds up the curing process and 
makes the product less susceptible to aging. This element is used in 
photoreceptors. This element has 8 naturally occurring isotopes. This 
element is present in coal up to 2 ppm. What element is being described?

Bonus question: Why did this element cause Dimitri Mendeleyev problems?

The Answer:

The element is Tellurium (Te! Te is used in a number of metal alloys used 
in the electronics industry such as tellurium copper and some stainless 
steels. Te is used to tint glass and ceramics. It is also added to lead 
(Pb)in batteries making them harder and more acid resistant. Elemental Te 
has low toxicity but does cause extremely bad breath and body odor for 
those working with it. 


Bonus Question Answer: The father of the Periodic Table, Dimitri 
Medeleyev, had lots of problems with the element Tellurium as its atomic 
weight was heavier than the element that followed it (Iodine). Te's atomic 
weight was found to be 128 but Iodine's was 127 so Medeleyev decided that 
one of the atomic weights must be in error. It took almost 50 years to 
determine why Te's position in the periodic table was correct. The 
dominate isotopes of Te are Te130 and Te128 which together account for 2/3 
of its mass giving an overall atomic weight of 127.6. Iodine has only one 
dominate isotope - I127 -giving it an atomic weight of 126.9.  (Denny 
Fritz, SAIC, provided the only correct bonus question answer)


The winner of the weekly quiz is Joe Russeau, Precision Analytical 
Laboratories, and he will get the services of Clumpy and Kloumpios for the 
week. The guys sent a text message from their cell phones saying they had 
a blast at Leland's, had a wonderful last day beer and burger party and 
were promptly heading for Joe's facility in Indiana. They also were 
extremely glad to get out of the path of Hurricane Irene but did assist a 
few folks near Leland's facility with hurricane proofing their houses 
before hitting the road.
