A solid in which electrons are able to move easily from one atom to another is called a conductor. Conductors allow electric current to flow freely through them due to the mobility of electrons. Metals like copper and aluminum are examples of good conductors.

A conductor
Charge is usually transferred by electrons because electrons are the negatively charged particles within an atom that are easily able to move from one atom to another, allowing for the transfer of electrical charge.
The material that allows electrons to freely pass from one atom to another is called a conductor. Conductors have loosely bound electrons that are able to move easily through the material in response to an electric field. Metals are examples of good conductors due to their abundance of free electrons.

Materials that allow electrons to travel easily are known as conductors. Some common examples of conductors include metals such as copper, silver, and aluminum. In conductors, electrons are able to move freely due to the presence of delocalized electrons in the material's atomic structure.
Metals are good conductors of electricity because they have free electrons that are able to move easily through the material, allowing for the flow of electric current. When a metal gives off or takes in electrons, it is essentially allowing these free electrons to move from one atom to another, creating an electrical current.
One material may be a better conductor than another due to its atomic structure, specifically the mobility of its electrons. Materials with more free electrons that are able to move easily will conduct electricity more efficiently. Additionally, the presence of impurities, temperature, and crystalline structure can also impact a material's conductivity.
Solids have tightly packed particles that vibrate in fixed positions, limiting their ability to move around and diffuse. Diffusion requires particles to be able to move freely and spread out, which is not easily achievable in solid materials due to their fixed structure.
there aren't none the hollow bones don't break as easily and they are able to produce bone marrow inside.
