Attractive forces are forces between particles that draw them together. They can be between atoms, ions, molecules or any other particles.
A type of chemical bond where one atom gives up an electron to another atom resulting in attraction between oppositely charged ions.
Covalent Bonding: A type of chemical bond where atoms share electrons creating an attractive force between them.
Van der Waals Forces: These are weak intermolecular forces resulting from instantaneous polarizations of molecules.
