3. . What are three examples of conductors and three examples of insulators?

## Step 1<br />Conductors are materials that allow the free flow of electrons. This is due to their atomic structure, which allows electrons to move freely. This property makes them excellent at conducting electricity.<br /><br />## Step 2<br />Examples of good conductors include metals such as copper, aluminum, and gold. These metals have a large number of free electrons that can move easily, making them excellent conductors.<br /><br />## Step 3<br />Insulators, on the other hand, are materials that do not allow the free flow of electrons. This is because their atomic structure does not allow electrons to move freely. This property makes them poor conductors of electricity.<br /><br />## Step 4<br />Examples of good insulators include rubber, glass, and plastic. These materials have a structure that does not allow electrons to move freely, making them poor conductors of electricity.
