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

Option (b) is the correct answer.

Explanation:

An atom consists of three sub-atomic particles, that is, there are protons, neutrons, and electrons in an atom.

Protons are positively charged, neutrons have no charge and electrons have a negative charge.

It is known that opposite charges attract each other. And a salt contains atoms of two or more different elements.  

Therefore, there occurs attraction between a proton and an electron which is responsible for the force of attraction between the particles in a salt crystal.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

that tool would be a compass
