Below are sample questions representative of the exercises included on this worksheet and related 11.36 Ionic Bonding, Lattice Energy, and Ionic Solids skill assessments:

Problem 1Difficulty: Mastery

A 2D checkerboard diagram is used to introduce ionic solids. What limitation should students remember?

AThe model proves ionic solids are made of flat covalent sheets only.

BThe model shows that all cations touch only one anion in real crystals.

CThe model proves lattice energy is independent of charge and distance.

DThe model shows charge alternation but not the full three-dimensional coordination or actual energy values.

Solution & Explanation:Simple 2D diagrams are useful for visualizing alternating charges, but real ionic crystals are three-dimensional lattices with specific coordination patterns and energy magnitudes.

Problem 2Difficulty: Mastery

Why can molten NaCl be electrolyzed while solid NaCl cannot be electrolyzed under ordinary classroom conditions?

AMolten NaCl contains neutral NaCl molecules, while solid NaCl contains no particles.

BSolid NaCl has mobile electrons, but molten NaCl has none.

CMolten NaCl has mobile Na+ and Cl- ions that can migrate to electrodes, while solid NaCl has fixed ions.

DMolten NaCl becomes a covalent liquid and no longer contains ions.

Solution & Explanation:Electrolysis requires charged particles that can move to electrodes. Melting frees ions from fixed lattice positions.

Problem 3Difficulty: Mastery

An ionic compound forms from M3+ and X2- ions. Which formula and lattice-energy reasoning are both correct?

AMX; the charges cancel because 3 and 2 are close in size.

BM2X3; the +3 and -2 charges create a large charge product for strong attractions.

CM3X2; the subscripts must match the ion charges exactly.

DM2X3; the high charges make the compound unable to form a lattice.

Solution & Explanation:Charge balance requires two M3+ ions (+6 total) and three X2- ions (-6 total). The charge product between neighboring ions is large, increasing attraction.
