Can an electrostatic charge exist in free air?

Or does it need containment or particles to stay together?

If it requires particles, then they would all need the same charge. What would prevent them being repelled from each other and stay coherent?

    No, an electrostatic charge exists on a surface, By definition.

    It is Coulomb field. It extends to infinity. Like gravity. It exists in empty space also.
