Hydrogen bonding does not involve bonding. It is an attraction between a hydrogen atom and either an oxygen, nitrogen, or fluorine atom. In this depiction, the hydrogen atoms of H2O molecules are attracted to the fluorine and oxygen atoms of the apatite molecule.
Since apatite is a polar molecule, it attracts other polar molecules and their oppositely charged ends. In this case, the positive potassium atoms of the potassium bromide molecules are attracted to the negatively charged fluorine and oxygen atoms of the apatite molecule.
Dispersion forces act upon any two adjacent molecules in a liquid. Therefore, any molecule next to an apatite molecule in a liquid would be affected by this force. In this case, hydrogen fluoride and apatite are engaged in this property
