Formula
- Lattice Energy Calculator calculates its result from Madelung constant, Cation charge, Anion charge, Ion separation (pm), Born exponent. It uses the formula Born–Landé model: U = −N_A M |z+z−| e²/(4πε₀r₀) × (1 − 1/n).. Change any input to recalculate the result instantly.
- The main inputs are Madelung constant, Cation charge, Anion charge, Ion separation, Born exponent. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Lattice Energy
- Madelung constant: 1.7476
- Cation charge: 1
- Anion charge: -1
- Ion separation: 282 pm
- Born exponent: 9
Using Madelung constant = 1.7476, Cation charge = 1, Anion charge = -1, Ion separation (pm) = 282, Born exponent = 9, the calculated result is -765.3383948915.
