Silicon, in its pure form, is:

1. A a semiconductor
2. B a conductor
3. C an insulator
4. D a superconductor

Correct answer: C — an insulator. From the official ISED question bank, verified word for word.

Why

In its pure form, silicon holds onto its electrons tightly, preventing electricity from flowing easily, which makes it an insulator. The full explanation — and one for every question — is in Pro.
