Answer:
A conductor is a material that permits electrons to effortlessly go through it. Copper is a good conductor. Note that the valence shell has just a single electron.
While;
Materials that don't conduct are named insulators.(i.e. glass, porcelain, plastic, elastic. The covering on electrical wire is an insulator.)
Insulators don't conduct since they have a full or almost full valence shell and along these lines their electrons are firmly bound.
