Hi Dave,
Thanks for the explanation. The statement of 46 isotopes is what really threw everyone off since it's specific.
I appreciate your work in coming up with these questions- it surely takes our minds off of other stressful work!
Thanks again,
Ron

Hi Ron - the number of isotopes is going to be somewhat dependent on which reference source I am using when putting the element clues together. That is one reason I try to give a set of clues that, when considered as a whole, can only point to one element. Most of the time that methodology has been successful but on occasion, our Technet community finds holes in the clue logic set. Hope that makes sense.
Dave

Doesn't Thulium have 58 Isotopes (23 Isomers, 34 Radioactive Isotopes plus the one stable)?

Subject: [TN] NTC Friday Element Quiz Answer
Hi folks - Here is the Friday Element Quiz Answer (sorry for getting this out late - blame it on Minnesota ice):
The Question:
This element has 46 isotopes but only one is stable. This element is so scarce that 500 tons of ore must be processed to extract 4 kilograms of the element. It has very few commercial uses - it has been used for portable x-ray sources and in laser applications. The dust of this element
is both toxic and explosive. What element is being described?
The Answer:
The element is Thulium (Tm)! Thulium derives its name from Thule, the Greek word for Scandinavia. Thulium is very rare in terms of being a Rare Earth Element(REE)- it ranks 16th out of 17th. Monazite sand contains about 50% REE content but of that 50% value, only 0.007% is thulium.
Tm-169 is the only stable isotope of thulium.
The winner of the weekly element quiz is Steve Gregory and he will get the services of Clumpy and Kloumpios for the week. The boys should be arriving at your facility anytime now.
So far Clumpy and Kloumpios have done the following:

- Tell the guys I'm giving them a late Christmas present, and they can spend the week at home with their wives fulfilling their own set of chores. Maybe they'll get a chance to get back to NC a little later on in the year, and it will be warm enough to go fishing at the coast.
