Question

which interaction is responsible for the force of attraction between the particles in a salt crystal? proton - proton proton - electron neutron - electron electron - electron

Explanation:

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 holds the particles together. Proton - proton and electron - electron interactions are repulsive forces, and neutron - electron interactions do not play a role in the ionic bonding of salt crystals.

Answer:

proton - electron
