[TN] NTC Friday Element Quiz:  The Question
Sent by:

Hi folks - here is the Friday Element Question:

The Question:

This element has been known since the 5th century B.C. and is believed to 
be first produced as a metal in 1250 A.D. This element is sometimes added 
to Pb plates as a strengthening addition. This element is typically a 
by-product from copper, lead and zinc ores rather than being mined for the 

sole purpose of its own recovery.  This element was used at one time for 
the control of boll weevil damage in cotton crops in Mexico and the United 

States until prohibited due to toxicity/environmental issues. What element 

am I?


The winner of this week's quiz will get to put Clumpy to work at their 
facility on a task of their choosing.

So far Clumpy has:

Week 1 Lamar Young, SCS Coatings 
- accomplished nothing (drank lots of coffee)

Week 2 Bev Christian, RIM 
- conducted REACH material testing

Week 3 Drew Meyer, Bench 
- Solderability testing and mowing the lawn

Week 4 Ian Fox, Goodrich 
- ???? Ian owes us a description

Week 4 Gary Ferrari, Garrick Global 
- ???? Gary owes us a description

Week 5 Fredrick Miller, Astrolab 
- ???? Fredrick owes us a description

Good Luck.
