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: Past Quiz winners/tasks: Week 1 Dick Krug, Spartan Complex Systems Week 2 Laura Turbini, IRC Week 3 James Head, Crowcon Detection Instruments Limited Week 3 Pat Goodyear, PGE Week 4 Joe Russeau, Precision Analysts Laboratory Week 5 Tom Carroll, Boeing Defense, Space and Security Week 6 Steve Gregory Week 7 Phil Kinner Week 8 Brian Ellis Week 9 James Head,Crowcon Detection Instruments Limited Week 10 Leland Woodall, CSTech Inc.

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.
