Hi folks - here is the Friday Element Quiz Answer:

The Question:

This element has a half life of approximately 24,100 years. This element 
has decreased electrical resistivity as the metal is warmed up. This 
element is one of the most toxic materials known - in terms of radiation 
and chemically. Inhalation of 100 mg of fine element dust will cause death 

in a few days. There is no commercial market for this element. What 
element is this?


Bonus Question: Name the Roman mythology connection of this element.


The Answer:

The element is Plutonium - Pu. Plutonium is unique in the elements as it 
can have 6 crystal structures (allotropism) depending on the temperature. 
Pu has the lowest thermal conductivity of all the metals. PuO2 has been 
used as a heat source in thermoelectric power supplies for the Voyager, 
Galileo and Cassini spacecraft.

The answer to the bonus question: Pluto was the Roman mythological god of 
hell.
