> The lattice energy depends on the attraction between the oppositely charged ions. The force of attraction F is directly proportional to the charges (q_1 and q_2) on the two ions and on the distance r between them. F = (q_1q_2)/r^2 The distance between the charges r is the sum of the ionic radii. r = r_"anion" + r_"cation" So the greatest attractions 2021-04-22 · The lattice energy is the energy released when the lattice is formed.

Q1. (8.24). (a) Does the lattice energy of an ionic solid increase or decrease (i) as the charges of the ions increase, (ii) as the sizes of the ions increase? (b) Arrange the following substances not listed in Table 8.2 according to their expected lattice energies, listing them from lowest lattice energy to the highest: MgS, KI, GaN, LiBr. According to the Equation, electrostatic attraction Answer: KI, LiBr, MgS, GaN Explanation: Ionic sizes are the deciding factor in lattice energy. The smaller the ion, the higher the lattice energy.

This tutorial covers lattice energy and how to compare the relative lattice energies of different ionic compounds.https://www.thechemsolution.com The lattice energy could be defined in two ways in Chemistry. Let us discuss the both of definitions one by one in this blog post. The overall potential energy of a chemical compound is also named as the lattice energy and it can be defined in terms of electrostatic or repulsive energy. The distance between ions is greater in "KI", so "KI" should have a lower lattice energy and a lower melting point than "NaBr". A simple extrapolation from "NaCl" through "NaBr" suggests that "KI" should have a lattice energy of about 680 kJ/mol and a melting point of about 700 °C.
