A lattice energy calculator helps determine the energy released when ions in the gaseous state come together to form a solid ionic compound. Lattice energy is an essential concept in solid-state chemistry and plays a key role in understanding crystal stability, solubility, and bonding strength.
The calculator typically applies the Born-Haber cycle or Coulomb’s law for accurate lattice energy computation.
How to Use the Lattice Energy Calculator
Step 1: Enter Ionic Charges
Provide the charges of the cation and anion (e.g., +1 for sodium () and -1 for chloride ()).
Step 2: Input Inter-Ionic Distance
Specify the distance between the ions in nanometers (nm) or meters.
Step 3: Provide Constants (if Required)
Some calculators may request the Madelung constant or dielectric constant for advanced computations.
Step 4: Calculate
The tool applies formulas like:
Where:
- = Lattice energy
- = Proportionality constant
- = Ionic charges
- = Inter-ionic distance
Example Calculation
For NaCl, with ionic charges of +1 and -1 and an inter-ionic distance of 0.28 nm, the calculator provides lattice energy in kilojoules per mole (typically around 786 kJ/mol).
