As the young graduate from the school for Alchemists crawled out the
pool his next door neighbor leaned over and said "crucibles". He didn't
meet Mrs. Robinson until later at the Toga party.

HI,

 General question if anyone knows. What techniques did these chemists
use
back in the 1800's to isolate element?

Subject: [TN] NTC Friday Element Quiz The Question

Hi folks - here is the Friday Element Quiz:

The Question:

        Only 5 metals have melting points higher than this element. It
is 
nontoxic and is used in biomedical implants. It is a constituent in 
stainless steel, in nuclear fission reactor core structures, and is a 
substitute for the element Ta for aqueous corrosion resistance
processing 
equipment. This element has nearly unlimited room temperature ductility 
characteristics. This element that had two different names up to  the 
early 1950's until the international chemist union settled the
discussion 
on which one was correct.  Who am I?

The Answer:

The element is Niobium! As the old adage states " you can spot old 
American metallurgists from a thousand miles away, those troglodytic
folks 
still say "columbium"! An English chemist, Charles Hachett identified an

element he named "columbium" in 1801 and a German chemist, Heinrich
Rose, 
identified an element he named "niobium" in 1846. It took a century of 
discussion before the element was officially named niobium in 1949! 


Eric Christison was the first to correctly (and incorrectly after 1949) 
answer to the quiz. I'll be shipping my chair to him and sitting on 
several cases of Diet Coke until we get our 2011 budgets.

Everyone have a great weekend.
