The Question: This element is extremely stable and almost completely non-reactive which is one reason for its name. Until 1957, the symbol for this element was a single letter. The atmosphere of Mars contains this element. This element is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents. This element is widely used in a number of spectroscopy applications (i.e. ICP, FIB, etc.). Name the element being described? The Answer: The element is Argon (Ar)! Argon derives its name from the Greek "argos" which means " inactive". Until 1957, the symbol for argon was "A", but now is "Ar" (its true, I looked at the 1927 Periodic Table I have). The atmospheres of Mars, Mercury and Titan (the largest moon of Saturn) all contain argon. Argon may be used as the carrier gas in gas chromatography and in electrospray ionization mass spectrometry; it is the gas of choice for the plasma used in ICP spectroscopy. The winner of the quiz will is Russell Kido, Practical Components and will get the services of Clumpy & Kloumpios for the week. The EQAB reviewed Doug's submission of "StableGon" and unfortunately the response was disqualified. Discussions with NASA experts on Mars could not confirm the existence of StableGon but EQAB would rule Doug's answer correct if the new Mars probe does find any evidence of the half fractional element in the future. Additionally, inquires into the IUPAC records show no evidence of the information Doug stated. So far Clumpy and Kloumpios have done the following: Past Quiz winners/tasks: Week 1 Ravinder Ajmani, Western Digital Week 1 Ron Feyereisen, SigmaTron Intl.
