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.

I have a guess, Iridium, ninth highest melting point, very resistant to corrosion. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of David D. Hillman Sent: Friday, April 23, 2010 8:20 AM To: [log in to unmask] 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.
