which interaction is responsible for the force of attraction between the particles in a salt…

Brief Explanations:

In a salt - crystal, there are ions. The force of attraction is due to the electrostatic force between oppositely - charged ions. Protons are in the nucleus and are positively charged, electrons are negatively charged. The proton - electron interaction is responsible for the ionic bond in a salt crystal which leads to the force of attraction between particles. Proton - proton and electron - electron interactions are repulsive forces (like - charges repel), and neutron - electron interactions do not contribute to the ionic bonding in salts as neutrons are neutral.

Answer:

proton - electron
