20. Consider the following representation of a 2p-orbital: Which of the following statements best describes the movement of electrons in a p-orbital? (A) The electrons move along the outer surface of the p-orbital, similar to a figure “8” type of movement. (B) The electrons move within the two lobes of the p-orbital, but never beyond the outside surface of the orbital. (C) The electrons are concentrated at the center (node) of the two lobes. (D) The electrons are only moving in one lobe at any given time. (E) The electron movement cannot be exactly determined.
