Calculate Lattice Energy





Formula

The formula to calculate lattice energy is:

\[ \text{LE} = \frac{K \cdot Q_1 \cdot Q_2}{R} \]

Where:

Lattice Energy Definition

A lattice energy is defined as the total energy released when two charged gas ions attract and form a solid.

Example Calculation

Let's consider an example:

Using the formula to calculate the lattice energy:

\[ \text{LE} = \frac{2.31 \times 10^{-19} \times 1 \times -1}{0.2} = -1.155 \times 10^{-18} \text{ J} \]

This demonstrates that with ion charges of +1 and -1, and a distance of 0.2 nm, the lattice energy is -1.155 x 10^-18 J. ✅
