Electrostatic forces between molecules are often called dipoles. And all the chemistry studied in your courses, Have dealt with intermolecular forces. Electrons are proton crazy. Dipole-dipole attractions occur because the opposite ends attract. I kind of dipole called hydrogen bonding.
Electrons are proton crazy.
The greater their atomic mass is, the greater they will attract. Electrons attract protons from other sources. And this is called Van der Waals forces. Electrons are proton crazy. Wish you would covalently bond with me my friend.
