Denny,
They can plate plastic buttons. That doesn't make plastic a metal.

Subject: Re: [TN] NTC Friday Element Quiz - the Answer

Hmm, bad choice.  Who do I want mad at me - Hillman or Christian?   How about this, from a hip-boot wearing plating guy - if you can electroplate it (passes current) - does that make it a metal?  Electroplated solder or nickel gold bumps on silicon have been standard practice for decades.  I know, I know, you will tell me silicon is a semiconductor.  I guess that makes it a half-metal for me. Now, either none or both are mad at me.

Dear Mr. Hillman,
 was a little taken aback when in an earlier quiz you labeled antimony as a
etal rather than as a metalloid, but I can live with it, I guess.  However,
or you to call silicon a metal is just too much!  In 57 years, 41 of those
s a chemist (I am counting from when I decided to be one in grade 9), I
ave NEVER before now heard anyone call silicon a metal.  As a main group
hemist (fluorine chemist actually), I consider it a non-metal and am
illing to concede it is a metalloid, but metal? Never! You are poaching,
ir. I will stop short of demanding satisfaction.  However, I do ask you to
espond and I also ask fellow TechNetters their opinion on this.

PS For those of you new to TechNet Dave IS a dear friend and this is all
retty well tongue in cheek.  And seeing this venue is overrun with
ngineers, rather than scientists, I highly expect I am going to be
ut-voted, shot down in flames, made into toast and other alliterations.

ubject: [TN] NTC Friday Element Quiz - the Answer
Hi folks - Here is the Friday Element Quiz Answer:
The Question:
The first "pure" use of this element began in 1823. This element is 
ometimes classified as a metalloid. The density of this element increases 
when it is melted. The native oxide of this element prevents further 
xidation of the element below 900C. What element is being described?
The Answer:
he element is Silicon (Si). Silicon is a metal that enables technology in 
 multitude of ways. Silicon is a deoxidizer in steel production, the 
asis for integrated circuits, glass, cement, protective coatings for high 
emperature applications, and families of polymers. Ge atoms are larger 
han Si atoms so an alloy of 85%Si and 15% Ge has an average interatomic 
pacing slightly larger than pure Si. When a pure layer of Si is deposited 
n the 85/15 alloy, the Si becomes strained resulting in a 70% faster 
ignal speed parallel to the surface! Less than 1% of the world's 
roduction of Si is the pure form but that 1% (approximately 40K 
ons/year) is roughly equal in total dollar value to the other 99% of the 
etallic Si production.

Lots of good guesses (this was one of the tougher quizzes) - the winner of 
his week's quiz is Bev Christian of RIM. Clumpy have to sneak onto the 
380 in Germany and head for Canada:
So far Clumpy has:
Week 1 Lamar Young, SCS Coatings
 accomplished nothing (drank lots of coffee)
Week 2 Bev Christian, RIM
 conducted REACH material testing
Week 3 Drew Meyer, Benchmark Electronics Inc.
 Solderability testing and mowed the lawn
Week 4 Ian Fox, Goodrich
 had an epic journey of travel
Week 4 Gary Ferrari, Garrick Global
 unknown
Week 5 Fredrick Miller, Astrolab
 unknown
Week 6 David Nelson, Raytheon
 Was a tackling dummy for Dallas Cowboys
Week 7 Graham Collins, L3 Communications
 Cleaned gutters and painted window trim
Week 8 Bill Noel, ITT Geospatial Systems Division
 unknown
Week 9 Steve Gregory of RD Circuits
 unknown
Week 10 David Bealer of Watchfire Signs
 descaled the in-line wash machine! Ouch!
Week 11 Dick Krug of Sparton Corporation
 assisted with AS9100 quality management systems requirements audit
Week 12 Steve Creswick of Balanced Enterprise Solutions
 Acted as Steve's "go fer" due to a broken leg!
Week 13 Gebhard Neifer, Delphi
 conducted a plasma pre treatment Taguchi DOE for a sealing process
Week 14 Bev Christian, RIM
 ????
Have a good weekend.
