Electrostatic interaction is the essence of chemical bond-ion bond formation, including electrostatic attraction and electrostatic repulsion. An ion bond is a chemical bond formed between anions and cations generated by atoms after gaining and losing electrons by electrostatic interaction. The nature of ionic bonds is electrostatic interaction. Since electrostatic attraction has no directionality, the interaction between anions and cations can be in any direction. As long as conditions permit, the surrounding cations can attract as many anions as possible, and vice versa, and the ionic bonds are not saturated. Different anions and cations have different radii and electrical properties, and the resulting spatial lattices of crystals are not the same.

Classification of electrostatic interactions

Ionic interactions involve the attraction of ions or molecules with full permanent charges of opposite signs. For example, sodium fluoride involves the attraction of the positive charge on sodium (Na+) with the negative charge on fluoride (F−)

Hydrogen bond (H-bond), is a specific type of interaction that involves dipole–dipole attraction between a partially positive hydrogen atom and a highly electronegative, partially negative oxygen, nitrogen, sulfur, or fluorine atom (not covalently bound to said hydrogen atom).

Halogen bonding is a type of non-covalent interaction which does not involve the formation nor breaking of actual bonds, but rather is similar to the dipole–dipole interaction known as hydrogen bonding.
