Formula and explanation
Formula: U = - (N A A z⁺ z⁻ e²)/(4 π ₀ r₀) (1 - (1)/(n) ight) Conditions: Ionic crystals. Brief Description: An approximate formula for calculating the lattice energy (energy released when 1 mol of crystal is formed) of an ionic crystal. It depends on ion charges, interionic distance, and the Born exponent.
