AP Chemistry
2.3 Structure of Ionic Solids
The table below provides the ionic radii for selected alkali metal cations and halide anions.
Based on Coulomb's law and the data in the table, which of the following correctly ranks the four ionic compounds in order of decreasing magnitude of lattice energy, and provides the correct justification?
| Ion | Ionic radius (pm) |
|---|---|
| \(\text{Li}^+\) | \(76\) |
| \(\text{Na}^+\) | \(102\) |
| \(\text{F}^-\) | \(133\) |
| \(\text{Cl}^-\) | \(181\) |
