Well 95% right :) Fluorine Greek word was originally suggested - Phthorine Bev Hi folks - Here is the Friday Element Quiz Question (sorry for being late, just got back from a tin whisker conference): The Question: This element is essential for humans and we consume 0.3 - 3 milligrams per day in our diets. However, it has also been shown to be an effective insecticide for cockroaches and ants. Chemists were aware of this element as early as 1670 but were unable to isolate the element and many became either ill or died as a result of their isolation attempts. Cattle grazing on areas contaminated by volcanic dust have become ill/lame due to the presence of this element. This element has one natural isotope. What element is being described? Bonus Question: What Greek word was originally suggested as the name for this element? -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Steve Mikell Sent: Saturday, September 17, 2011 1:55 PM To: [log in to unmask] Subject: Re: [TN] NTC Friday Element Quiz - the Question Dave, I'm guessing Flourine.........
