Insulators.
A materiel that allows an electric charge to pass through it is an conducter (copper, for example)
A conductor is a material in which charges can move easily.
As unsatisfying as I'm sure you'll find this, that depends on your definition of "electricity." If you mean electricity in the most conventional sense of an electrical current, electricity can move through any medium in which charge carrying quantons (protons, elecrtons, etc) can move at least somewhat freely.
move back and forth in a circuit. :)
There are two types of charges: positive charges and negative charges. Positive charges are immobile, and are found inside the nuclei of atoms as Protons. Negative charges can be mobile, and have the source of electrons. These orbit the nuclei of atoms, and can be stripped from the atoms to be used as mobile charged through conductors, such as electricity moving through wires.

Rubber is generally considered an insulator, meaning it does not easily allow charges to move freely through it. This is due to the polymer structure of rubber that restricts the flow of electrons.
Conductors, such as metals.
Materials that allow electric charges to move freely through them are called conductors. Examples include metals like copper, silver, and gold. Conductors have low resistance to the flow of electric current.
Insulators, such as rubber, plastic, or glass, do not allow the passage of electric charges through them because they hold onto their electrons strongly and do not allow them to move freely. This prevents the flow of electricity through the material.
Insulators
An insulator is a material that does not allow charges to move freely. Insulators have a high resistance to the flow of electric current, leading to the confinement of charges within a specific region. Materials like rubber, glass, and plastic are examples of good insulators.
An insulator is a material in which charges cannot move freely. Insulators have tightly bound electrons that do not easily flow in response to an electric field. Examples of insulators include glass, rubber, and plastic.
The electrons of an atom can note freely around an atom.
A charge moves easier through metal because metals are good conductors of electricity, allowing the charge to flow more freely. Air is a poor conductor of electricity, so charges do not move as easily through it.
If something doesn't let electrical charges to flow through easily, it is called an electrical insulator.
Charges leave the dry cell. Charges move through the switch. Charges move from the switch to the light. Charges move through the light bulb. Charges move through the wire leading back to the dry cell.
