Subject: [TN] Element Quiz Question
Hi folks - here is the Quiz:
The Question:
This element is one of only four radioactive elements (along with bismuth, protactinium and uranium) that occur in large enough quantities on Earth for a standard atomic weight to be determined. Four-fifths of this element that was present at Earth's formation has survived to the present. This element is extremely radioactive with most of its non-radioactive commercial applications being phased out for other materials starting in the 1950s. However, many of the Technet community have indirectly interacted with this element on family camping trips. What element is being described?
The winner of the quiz will get the services of Clumpy & Kloumpios for the week.

- I will appreciate if poor guys can fill time sheets of whole month for me. Sorry for such an awful task, didn't choose to be this merciless...
Week 95 Ravinder Ajmani, Western Digital
- I have a very hectic schedule next week, as I need to make an inventory of all the good measurement probes in my lab. This will require careful examination of each probe tip for any possible damage. So both Clumpy and Kloumpios will be a big help. They can enjoy the weekend visiting Santa Cruz, Monterey, and Carmel.
Week 96 ????
- assisted with ????
I hope everyone has a awesome week!
