Question

why electron do not flow from positive terminal to negative terminal and why only electrons move why proton do not move ?​

Answer 1

Answer:

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.

Protons interact in ways that electrons do not. Electrons are not affected by the strong force, and so they only get trapped by the electrical attraction to the nucleus which is much weaker in ionized atoms. Therefore it is easier for electrons to move away from one atom to another, transferring charge

Explanation:

Answer 2

The atoms of a wire themselves, however, do not move. Because the protons in the nucleus of the atom don't move, the protons don't affect the movement of electrical charges or the magnetic fields; because the electrons move, the electrons affect the electrical charges and magnetic fields.
