Question

why are non-metals used as insulators​

Answer 1

Answer: In non-metal elements the electrons are held much more tightly in the chemical bonds that hold the atoms together. This means they will resist the motion of charge through them, i.e they have a very high electrical resistance. We normally call the materials with very high resistances an insulator.
