Subject: [External] [TN] Element Quiz Question
The Question:
A compound of this element was the primary ingredient in rat poison until a
1972 Executive Presidential Order banned its commercial use. This element and its compounds are extremely toxic to everything and it was once considered the "poison of choice" by assassins. Nearly 70% of this element's commercial use is in the electronics industry for making photoresistors and selenium rectifiers. One of the element's nuclides is still used in stress tests for coronary artery disease risk assessment. What element is being described?
The winner of the quiz will get the services of Clumpy and Kloumpios for the week.

Week 69 Mordechai Kirshenbaum
- but I don't want the brothers to travel so far away (they already had been in Israel several months ago)...so they get the week off!
Week 70 Doug Pauls, Rockwell Collins
- The boys will be glad to be home and see the wives and family for a long weekend. They can help me with an 86000 lines of data statistical analysis, but then they get the weekend off.
Week 71 Eray Canli, ANDAR Electromechanical Systems
- Boys can leave as soon as we finish forging three Damascus steel knives together, from a Vanadium doped leaf spring of an old truck...and in addition to their knives, I'll buy them cold beer for their effort and sweat!
Week 72 Russell Kido, Practical Components
- I'll have the boys check the Saber kits. I'm staying as far away as possible!! They can help me situate some new mattresses and since they have some 'hops' and can 'sky' for being little guys, they can continue to teach my daughter their skills in jumping, rebounding and shooting. They can also drive me from my glaucoma test and then soak up some rays.
Week 73 ????
- assisted with ????
I hope everyone has a awesome week!
