Q. What is the only non-metal to conduct?
I suspect you mean electricity, so it's water.
Which in pure form doesn't conduct either.
Presume this is electricity in which case isn't it water?
Not Carbon then??
(Sis Yr9 homework)
I think the word element was missing from the question.
And the answer is Carbon.
Edit: Gina posted while I was typing - honest.
Good point and stonking answer.
Steve is correct. Carbon is a resistive conductor.
Technically a more accurate answer (diamonds don't conduct, do the other forms of carbon?)
IIRC 'black' carbon - like coal - can conduct but not very well, depending up on what it is.
Or a TTF-TCNQ plastic composite
Now, that would be brilliant as a homework answer..
Selenium, as used in photocells
Isn't selenium a metal.?
What about silicon.?
No, selenium is a non-metal
In fact there are very many non-metals that conduct electricity
As is Selenium.
Super cooled polymers - in fact its just a flow of electrons so a lot of things will conduct, they will just have a very high resistance and so generally not be useful.
Thanks, sorry about the misleading question, it's how it was written on their question paper!!!
True but selenium is a non-metal whereas silicon is a metaloid
I've noticed that on son/daughter's GSCE papers, questions are written for the syllabus and often very subjective or inaccurate. I have seen multiple choice questions where more than one answer it technically correct (if you have a little more understanding than is needed for the syllabus). And often all that is needed to is a simple modification to the question (like including the word "element"). Not like it was in my day...
