Hi Guy - oops, sorry about that! BCC stands for Body Centered Cubic 
crystal structure. The metallic elements can be classified in different 
crystal structures: Triclinic, Monoclinic, Orthorhombic, Tetragonal, 
Hexagonal, Rhombohedral, and Cubic. Each of the crystal structures can 
then be subdivided into Simple, Face Centered and Body Centered. And that 
was probably wayyyyy more metallurgy than ya wanted but it makes 
determining the Friday Element Quiz answer much more manageable.

Ir has a Face Centered Cubic (FCC) crystal structure so you get a Mulligan 
and can take a second guess.

Dave

RE: [TN] NTC - Friday Element Quiz






What is a BCC metal? 
I have a guess, 
Iridium, ninth highest melting point, very resistant to corrosion.

Subject: [TN] NTC - Friday Element Quiz

Hi folks! Ok, its Friday so its time for another element quiz:

The Question:
        I am a ductile BCC metal and one of the few BCC metals that  has 
no ductile-to-brittle transition. My elemental name is part of Greek 
mythology.

Bonus Points: 
        Name this metal's greatest attribute and its melting temperature 
rank with respect to all of the metals.


I am pretty sure that everyone will be able with some sleuthing to figure 
out which element but the hard part of the question is getting the bonus 
points!

Good luck and again  this week, the winner will get to claim Doug's desk.
