Do protons move with or against electric field?

WebIn answering the question "Why do "Electrons Move", you say "With a strong enough force, it is possible to give an electron enough energy to knock it up to a higher energy orbital, or even completely off of the atom (if the force which is giving it the energy to move around is stronger than the electric force holding it near the nucleus). WebSo can you view a proton transfer as just a special case of nucleophilic attack? What you are describing is in many ways a generalization of Lewis acid-base theory -- the nucleophile as an electron donor (Lewis base) attacking an electrophile as an electron acceptor (Lewis acid). While the two concepts are not completely congruent (Lewis ...
