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
