<p>RHSA SNC1D: Electricity Name: ______Conductors and Insulators Metals are good conductors. Conductors are substances that let electrons move easily from one atom to the next atom. Examples of good conductors are gold, silver and copper.</p><p>An insulator is a substance that does NOT let electrons move easily from one atom to the next atom. Examples are plastic, rubber and wood.</p><p>In an insulator the electric charge stays in one location. This is how we are drawing the charge diagrams for static charges by friction or contact.</p><p>Insulator - Negative Rubber 8+ 12-</p><p>In this example the rubber was rubbed on the left side by silk and got a negative charge.
