Question

Which material is likely to slow the flow of electric charges the most ? explain.

Answer 1

Metal as it is a conductor of electricity

Answer 2

Non metals

Step-by-step explanation:

Atoms of metals do not hold their electrons to themselves. Instead they allow them to float around them delocalised. This is important because it is this characteristic that allows metals to be good conductors of electricity since electrons are free to move around to carry a charge.

With the exception of carbon and silicon, non metals do not have this characteristic. Each atom hold on to its electrons within their orbits for the most part. This makes non metals very pour at allowing charges to flow through them.
