HC Lattice Energy & Ionic Solids

Coulomb's law says that the force between any two charges depends

• directly on the size of the charges

• inversely on the square of the distance between the charges

• both are correct

Which of the following has the smallest lattice energy?

• MgCl₂

• SrCl₂

• MgF₂

• SrF₂

Which of the following is NOT a property of ionic compounds?

• They conduct electricity when molten

• They conduct electricity when in solution

• They have high boiling points

• They are insoluble in water

Ionic compounds are solids at room temperature because....

• they consist of fully charged ions attracted to each other that minimizes the movement of atoms

• they have weak intermolecular forces

• they have a lattice structure

Rank the compounds below from highest to lowest lattice energy: NaBr, AlN, BeO, Li₂S

• AlN > BeO > Li₂S > NaBr

• NaBr > Li₂S > BeO > AlN

• BeO > Li₂S > AlN > NaBr

• AlN > Li₂S > BeO > NaBr
