Lattice Energy Calculator
Calculate lattice energies for ionic compounds using the Born-Lande equation. Compare experimental and calculated values.
Calculation Mode
Born-Lande Equation:
U = (N_A * M * z+ * z- * e^2) / (4 * pi * epsilon_0 * r_0) * (1 - 1/n)

Factors Affecting Lattice Energy:
- Higher ionic charges increase lattice energy
- Smaller ionic radii increase lattice energy
- Crystal structure (Madelung constant) affects energy
Lattice Energy Trends
Alkali Halides
LiF > NaF > KF > RbF > CsF (decreasing cation size)
Charge Effect
MgO >> NaCl (2+ and 2- vs 1+ and 1-)
