Here is the Element Quiz Answer

The Question:
This element is part of scintillation counters. This element is the most
reactive of the Earth metals and therefore is not found in its metallic
state on Earth. Light is strong enough to knock electrons off this element
making it useful as part of coatings for photoelectric cells. The words
"bluish gray". Which element is being described?

The Answer:
The element is Cesium (Cs). Cesium has several long lived isotopes so it
has important commercial applications as a beta particle generator. CsI is
used in Geiger counters (aka scintillation counters). The first Cesium
atomic clock was created in 1955 at the National Phyiscs Laboratory in the
UK. Mercury is the only elemental metal with a melting point (-38C) lower
than cesium (29C). Cesium is derived from the Latin "caesius" which means
"bluish gray" representing its spectroscopic analysis lines first observed
by Kirchhoff and Bunsen in 1860.

The winner(s) of the weekly element quiz is Graham Collins, Sunsel Systems
and he will get the services of Clumpy and Kloumpios for the week. Greg
Munie and Graham both submitted the correct answer but Graham's response
made it thru the Rockwell Collins firewall  just seconds before Greg's
answer. And EQAB gives honorable mention to Mike Fenner for the "English"
spelling of caesium!! (Or is that Latin?)

So far Clumpy and Kloumpios have done the following:

Week 73 Torsten Hagge, Kristronics GmbH
- Clumpy and Kloumpios have been picked up at Hamburg airport and are
looking forward to help with some laboratory work, as until now we havenĀ“t
found anybody to run shortage tests of several kW... behind this they get
the fantastic chance to redefine physical thermodynamic laws as required by
car manufacturer and next weekend I will spend them a Berlin visit, where
they can take off to US from the disaster airport

Week 74 Greg Munie, IPC
- Always a pleasure to see the guys again. And they have a treat coming up:
At last it'll be above freezing for a couple of days! So I'll put them
together sorting tools in the Abbey workshop. Should keep 'em out of
trouble for the week!

Week 75 Doug Pauls, Rockwell Collins
- I think, with tomorrow being Valentines Day, I will have the boys come
home
and spend a week snuggling with their wives.

Week 76 Graham Collins, Sunsel Systems
- assisted with ????


Everyone have a safe week.
