The Lattice Energy Calculator serves as a virtual compass in the realm of ionic compounds. It precisely calculates lattice energy, a key parameter defining the stability of these compounds. By employing Coulomb’s constant and charges of ions, coupled with the distance between their centers, the calculator unveils the energy holding the ionic lattice together.
Formula of Lattice Energy Calculator
The fundamental formula powering the Lattice Energy Calculator is expressed as follows:
U = - (k * Q1 * Q2) / r
Where:
- U: Lattice energy.
- k: Coulomb’s constant (8.988 × 10^9 N·m²/C²).
- Q1 and Q2: Charges of the ions in the ionic compound.
- r: Distance between the centers of the ions in meters.
Now, let’s delve deeper into the components of this formula to unravel its significance.
