Answer:
Electrons are able to move through a wire or conducting material because they are negatively charged particles that are free to move within the material. When a voltage is applied to the material, the electrons are pushed in a specific direction, creating a flow of electrical current. This movement of electrons occurs because the material contains a lattice structure of atoms, with each atom having outermost electrons that are loosely bound to their parent atoms. These loosely bound electrons are called "free electrons" and are responsible for conducting electricity through the material. When a voltage is applied, it creates an electric field that interacts with the free electrons, causing them to move in a particular direction. This movement of electrons creates a current flow through the material.
