It has been found that for a change of CN from 6(NaCl) to 8(CsCl), r o increases by 3.7 % whereas M increases only by 0.9 % (1.74 to 1.76). Eg sodium ion has a greater charge density than potassium ion. How is this possible? Match. Compare with the method shown below. I found a definition: lattice energy: the energy required to separate the ions or molecules in a mole of a compound by infinite distances. - the energy change when one mole of an ionic compound is formed from its separate, gaseous ions, under standard conditions . Let's also assume that the ions are point charges - in other words that the charge is concentrated at the centre of the ion. Created by. There is a tug of war between M and r o.-3. Theoretical values for lattice energy. Anonymous User Chemistry IIT 25 Aug, 2018 178 views. The size of the lattice enthalpy depends on the size and charge on the ion.
