The compound with the most exothermic lattice energy in each of the following pairs of ionic substances is Ca3N2.
What is Lattice energy?
- When ion pairs with opposing charges in the gas phase combine to create a solid, lattice energy is released.
- Lattice energy becomes weaker the lower you go in a group.
- As one descends a group, the atomic radius grows.
- As the atomic radius rises, the lattice energy falls because the force of attraction is inversely proportional to the square of the distance.
- As the charge's size rises, lattice energy rises as well.
- The product of the particle charges determines the force of attraction in a direct proportion.
- As a result, lattice energy rises as the charges do.
- Conclusion: The top of the Periodic Table will include the salts with the highest ionization energy and highest charges.
