Select all cases in which the attraction between units in the solid can best be classified as electrostatic bonding forces.
Electrostatic bonding forces relates to covalent compounds and the shared pair of electrons, it is when the nucleus of one atom attracts the electron of another atom and the electrons become shared between the two atoms.
