What kinds of interactions were overcome during the solution process?

During the solution process, ion-ion interactions were overcome in NaCl. In the water molecules, LDFs, H-bonding and dipole-dipole interactions were overcome.

Is there an attraction between two neutral helium atoms?

However, the van der Waals force exists between helium atoms as shown by the existence of liquid helium, and at a certain range of distances between atoms the attraction exceeds the repulsion. So a molecule composed of two helium atoms bound by the van der Waals force can exist.

Is there attraction between two neutral helium atoms?

Thus, as the electrons in one atom move around it, they will tend to synchronize to some extent with the motion of the electrons in the other atom. Overall there will be a force of attraction between the two helium atoms.

Can two helium atoms bond?

Helium is an inert gas whose atoms don't like to form bonds with others. But under particular circumstances, the atoms can be brought together to form diatomic (He2) molecules, says Jérémie Léonard, a graduate student at the ENS.

What causes attraction between two helium atoms?

However, due to the constant motion of electrons, there may be a temporary imbalance in the electron distribution of one helium atom, resulting in a temporary dipole moment. This dipole moment can induce a dipole moment in the neighboring helium atom, leading to the attraction between them.

What is the force of attraction between helium atoms?

Explanation: The force of attraction between helium atoms is primarily due to London dispersion forces.

What interactions are present in NaCl aq?

Explanation. The intermolecular forces associated with Sodium Chloride (NaCl) primarily involve ion-dipole interactions. NaCl is an ionic compound, and when it dissolves in a polar substance like water, the ions Na+ and Cl- separate or become solvated.
