Is it relatively easy to move an electron from the valence ring of conductor?

Yes, it is relatively easy to move an electron from the valence band of a conductor. Conductors, such as metals, have a high density of free electrons due to their atomic structure, allowing electrons to move freely under the influence of an electric field. This movement is facilitated by the low energy required to overcome the binding forces in the valence band, making electrical conduction efficient. As a result, conductors readily allow the flow of electric current.
