Difference between ionic bonding and ion-ion interactions?

Postby Brian Bui 3H » Wed Nov 11, 2020 11:59 am

What is the difference between ionic bonding and ion-ion interactions (if any)? I know that ionic bonding is a form of intramolecular force, but I'm not sure what the distinction is between this and ion-ion interactions, as ion-ion interactions were "introduced" along with the rest of the intermolecular forces.

Thank you!

The basic difference is that ionic bonds occur between atoms that form a salt, like you said, it is intramolecular. Ion-ion interactions are not necessarily bonds, but rather interactions because they occur when charged molecules themselves interact, so intermolecular forces. That is the basic difference, ionic bonds form molecules while ion-ion interactions are more like attractive forces that align these charged molecules.

I am also confused about this because in the lecture on Monday, Dr. Lavelle listed the Na+ Cl- reaction under ion-ion interionic attractive forces, when I thought these two formed an intraionic ionic bond.

Ionic bonds refer to the interaction within one molecule. Ion-ion interactions refer to the interactions between two ions or two molecules.

Ionic bonding is within one compound, like the bonding of Na+ and Cl-. Ion-ion interactions would be the attractive force felt between two oppositely charged ions, that aren't bonded together yet.
