Hi folks - Here is the Friday Element Quiz Answer:
The Question:
A compound of this element is considered by many chemists to be the most
powerful base to ever be discovered. The pure element was not isolated
until 1875. This element is used in the polishing of high refraction
lenses for telescopes. The words "sky blue". What element is being
described?
The Answer:
The element is Cesium (Ce)! Cesium hydroxide is easily manufactured by
dropping cesium metal in water - the very violent reaction produces
hydrogen and cesium hydroxide. Hillebrand and Norton were able to first
produce pure Ce in 1875 despite Ce being detected by chemists as early as
1803. The element name is derived from the Latin coesius - "sky blue" for
the element's characteristic blue lines of its spectrum.
Lots of correct answers this week but the winner of the weekly element
quiz is Joe Russeau, Precision Analysts Laboratory, and he will get the
services of Clumpy and Kloumpios for the week. The boys are eager to leave
Pat's task and head over to Joe's lab (they have decided they don't like
shoveling U-02 pellets).
So far Clumpy and Kloumpios have done the following:
Past Quiz winners/tasks:
Week 1 Dick Krug, Spartan Complex Systems
- Clumpy and Kloumpios arrived and were happy to get some warm weather.
Saturday they helped rake leaves (yes it's fall in Tampa) then went to the
Florida State Fair. They seemed most interested in some of the new
tractors, muttering something about the closed cab would be a more
comfortable ride, but they also took advantage of the opportunity for Fair
food. I couldn't believe how much deep fried food they ate - Snickers,
butter, burgers, ..., you name it. Yesterday they didn't feel good so
just sat around in the sun most of the day. This week I'm going to pick
their brains on how to improve our ECN implementation process. If they
can't contribute much I'll send them back to the fair as sort of a winter
vacation.
Week 2 Laura Turbini, IRC
- unknown
Week 3 James Head, Crowcon Detection Instruments Limited
- assisted with "haring"
And Pat Goodyear, PGE
- This time the boys will get to do some REAL work, they each have scoop
shovels and at present are shoveling piles of U-O2 pellets for refueling
the cook pot. We are in the middle of a 60 day refuel outage so their
help came at an opportune time, the majority of our contract crew left
this evening, (laid off). They are however complaining that it is hot
and they have been working in dry suits and sweating profusely, and they
have no beers to drop, not allowed on the property. I offered them Gator
aid but they just laughed. I asked them if they knew anything about
electronics and they could work with us technicians, but they just mumbled
about John Deere tractors. They will be working the next 3 days around
the clock, they will get rest when they are done, we have to get back on
schedule.
Week 4 Joe Russeau, Precision Analysts Laboratory
- assisted with ????
Everyone have a safe week!
