Interactions between Ions and Molecules
In the chart we made in week 5 on Friday, on the interactions between ions and molecules, there are certain energy values labelled and I don't understand what they mean, can someone help?

Re: Interactions between Ions and Molecules
I think it represents the energy that is released if the intermolecular force is broken. The value is negative because energy is being released rather than stored up as potential energy. The largest negative value is in the ion-ion interaction because a cation and anion will have a large attraction due to electron pull, meaning it stores the most potential energy in its attraction.

Yes, pay attention to the magnitude of the energy values. The greater the magnitude, the stronger the bond as it requires more energy to break that bond

If magnitude is greater, the bond is harder to break, because it has the most potential energy stored in its bonds.

For the record, anything on that slide will not be included on the midterm.

Re: Interactions between Ions and Molecules
For example, a hydrogen bond would have an energy of a greater magnitude (a larger negative number) because they are much stronger and require much more energy to break than a dipole-dipole interaction.
