Hi gang! Ok, here is the Friday Element Quiz:

The Question:

This element expands during solidification which is odd behavior for a 
metal and a very active topic of materials research. This element has the 
highest diamagnetism of any metal.  The electrical conductivity of this 
element's solid phase is lower than it's liquid phase. This element is 
normally nontoxic to humans but cases have been documented where bacteria 
have converted pharmaceuticals containing this element from water 
insoluble to water soluble compounds resulting in poisoning. This element 
is produced as a by product of Cu and W mining.  Who am I?


Doug is on vacation this week so we are giving away is desk chair as the 
prize.


Good Luck.
