The term for a solid object that allows free electrons to move easily through it is a conductor.

Here's why:

* Conductors are materials that allow electricity to flow through them easily. This is because they have free electrons that can move throughout the material.

* Free electrons are electrons that are not tightly bound to the atoms of the material and can easily move when an electric field is applied.

Some common examples of conductors include:

* Metals (like copper, silver, gold)

* Graphite

* Some solutions (like saltwater)
