Hi folks - Here is the Friday Element Quiz Answer:
The Question:
This element is used in high temperature ceramics creating some of the
most refractory materials known - an alloy using this element has a
melting point of 3310C. The first pure sample of this element was made in
1925. This element has six naturally occurring isotopes. This element
plays no know biological role and poses no environmental threat to plants
or animals. What element is being described?
The Answer:
The element is Hafnium (Hf)! Hafnium carbide is the alloy with the melting
point of 3310C. Hafnium and zirconium are chemically very similar thus the
reason for why it took so long to "discover" Hafnium. In fact, once a
sample of pure Hafnium was created and its atomic weight accurately
measured, the recognized atomic weight of zirconium had to be revised.
Many samples of pure zirconium were found to contain as much as 5% Hf.
Hafnium was the second to last of the non-radioactive elements to be
discovered.
The winner of the weekly element quiz is Gebhard Neifer, Delphi and will
get the services of Clumpy and Kloumpios for the week. Phil Kinner named
the right alloy but not the correct element (soo close). Just a note - I
won't repeat an element in the weekly quizzes until we have gone
completely through the entire Periodic table - and we have a long way to
go. The boys are on their way to Gebhard's facility today.
