Hi folks - Here is the Friday Element Quiz Answer:
The Question:
This element is used for research purposes only. There are no commercial
outlets for the element as Sodium can be used to accomplish the same tasks
at a much lower cost. This element is more expensive than gold or platinum
(*** per my reference source). A pure sample of this element was not
produced until 1928. Apples contain 50 ppm of this element but plays has
no known biological role.
Bonus Question: Name the mineral that contains this element.
The Answer:
The element is Rubidium (Rb). Rubidium was first reported in 1700's by
Nicholas Poda. Credit for discovery of the element goes to Robert Bunsen
and Gustav Kirchohoff in 1861. The first pure sample of the element was
produced in 1928 by Louis Hackspill. Rb has been used as a 'getter' in
vacuum tubes to scavenge trace oxygen and rubidium carbonate is used to
make special types of glass but very few other commercial applications
exist. There are a number of commercial applications were Rb could be used
but Sodium has been shown to accomplish the same end result for a fraction
of the cost.
Bonus Answer: Lepidolite with contains approximately 1.5% Rb.
There were lots of good guesses (Bev - loved your process of elimination
approach) but Brian Ellis was first across the finish line. The Clumpy and
Kloumpios celebrated the 4th of July with Scott Post (rumor has it they
grilled hot dogs, made handcranked ice cream, and saw a great fireworks
show)then used their Technet connections to catch a "stealthy" ride to
Cyprus. I had no idea Clumpy and Kloumpios knew how to sky dive! They
should be dropping in on Brian's house today ready for a task.
