What bond occurs between two oppositely charged particles which is the stongest noncovalent force that occurs over greater distances? This bond also can be weakened significantly by water molecules which water can interfere with bonding.

van der Waals forces

Explanation:
Detailed explanation-1: -The ion-ion, dipole-dipole, and ion-dipole interactions between oppositely charged particles is the strongest non-covalent bond.
Detailed explanation-2: -Intermolecular forces are non-covalent interactions that occur between different molecules, rather than between different atoms of the same molecule.
Detailed explanation-3: -Nevertheless, a number of gas-phase studies have demonstrated that noncovalent bonds can be stronger than covalent bonds.
Detailed explanation-4: -Ionic bond, also known as electrovalent bond, is a type of bond formed from the electrostatic attraction between oppositely charged ions in a chemical compound. These kinds of bonds occur mainly between a metallic and a non metallic atom.
