2.2-2.3: Intermolecular Forces, Potential Energy, Lattice Energy, and Properties of Ionic Compounds

Flashcards to review 2.2-2.3

Intramolecular forces

Attractive forces that hold 2 atoms together in a bond.

Why do atoms form bonds?

Atoms form bonds to lower potential energy and become more stable.

What does negative potential energy cause?

Attraction

What does positive potential energy cause?

Repulsion

What is Bond Length?

Distance between two nuclei.

What is Bond Energy?

Energy needed to break the bond.

What length do strong bonds tend to be?

Short

Do high order bonds or low order bonds lead to strong bond?

High order bond

What leads to lead to greater Lattice energy?

Stronger attraction

When do Ionic bonds have strong attraction?

Charges are large, and ions are small

How does Ion size affect attraction?

Larger ion size leads to less attraction, and smaller ion size leads to more attraction.

Melting point and Boiling point are high when…

Lattice energy is high

What is a salt?

Any Ionic compound.

What does Lattice shape lead?

Crystal like structures

When are Ionic Compounds conductive?

When they are liquid
