Hillman Sent: Friday, July 09, 2010 5:40 AM To: [log in to unmask] Subject: [TN] NTC Friday Element Quiz Hi folks - here is the Friday Element Quiz: The Question: This element was first discovered in 1898. This element forms a black nitride when exposed to air and reacts strongly with water. This element is a "bone seeker" as the human body metabolizes this element in a similar fashion to Ca and incorporates it into bone tissue elevating cancer risks. The longest lived and most common isotope of this element has a half life of 1600 years. This element was once widely used as a constituent of self luminous paint but the radiation safety issues eliminated this application. What element am I? This winner of this week's quiz will get a portion of Doug's cubical (don't know which part, depends on what we can dismantle while he is at today's staff meeting). Good Luck Dave Hillman Rockwell Collins [log in to unmask] ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
