Here is the Element Quiz Question:

The Question:
This element is a metal and has a large variety of commercial applications.
It can be found in nature as a free element and is one of the best known
element despite only being the 35th most abundant on Earth. The element is
mentioned in the Bible and was known to ancient civilizations. This element
has been poisoning humans for hundreds of years. This element is used in
the Oddy test. Which element is being described?

The Answer:
The element is Lead (Pb). Lead is used in hundreds of commercial
applications and has equally been shown to be toxic in hundreds of ways.
Lead was added to wine, used in paint, used in gasoline and in cosmetics
before its toxicity was fully understood. Lead chromate (PbCrO4) is a safe
yellow pigment and lead azide [Pb(N3)2] is used as a detonator of
explosives. Lead derives its name from the Latin word "plumbum" which is
the origin of the English word "plumbing", all associated with the use of
lead for water pipes in the Roman Empire.

The Oddy test is a procedure created at the British Museum by conservation
scientist William Andrew Oddy in 1973,[in order to test materials for
safety in and around art objects. This test calls for a sample of the
material in question to be placed in an airtight container with three
coupons of different metals—silver, lead, and copper—that are not touching
each other or the sample of the material.[3] The container is sealed with a
small amount of de-ionized water to maintain a high humidity, then heated
at 60 degrees Celsius for 28 days. An identical container with three metal
coupons acts as a control. If the metal coupons show no signs of corrosion,
then the material is deemed suitable to be placed in and around art
objects. The Oddy test is not a contact test, but is for testing
off-gassing.


The winner of the quiz is Jerry Dengler, Pergamon Corp. and will get the
services of Clumpy and Kloumpios for the week.

The EQAB was quite impressed with Doug's submission of "solomonium" but due
to he submitted silver as his first response, all other submissions are
null and void. Additionally, William Oddy is alive and breathing which
conflicts with some of Doug's details. EQAB did find it interesting that
nearly everyone but Doug does not survive interactions with the half
fractional elements!


So far Clumpy and Kloumpios have done the following:
