The lattice energies for NaCl most often quoted in other texts is about 765 kJ/mol. The lattice energy is the total potential energy of the crystal. Next, consider that this equation is for two ions acting on each other alone, while in a lattice each ion is acted on by every other ion at a strength relative to their interatomic distance. Add the changes in enthalpy to turn one of the elements into its gaseous state, and then do the same for the other element. In calcium chloride, the calcium atom donates its two electrons and become cation whereas each chlorine atom gain one electron, donated by Calcium, and get a negative charge. However, when plugging in a value, determine whether energy is released (exothermic reaction) or absorbed (endothermic reaction) for each electron affinity. First equal the formation enthalpy to the sum of all the other enthalpy's and use letter X to represent the lattice enthalpy . Skill:Explain the trend of lattice energy. EA of Cl(g) = -349 (Electron affinity of Cl) Hsub of Na = 108 kJ/mol (Heat of sublimation) Next, the electron affinity of the nonmetal will be subtracted from the previous value. There are many other factors to be considered such as covalent character and electron-electron interactions in ionic solids. Ca^2+(g) + 2Cl^-(g) --> CaCl2 dH = lattice Even though this is a type of potential energy, you can't use the standard potential energy formula here. Lattice energy i s the heat of formation when one mole of crystalline ionic solid is generated from its constituent ions in their gaseous state. In covalent bonding, the ionization energy of the atom is very high that it cannot donate its electron or electron pair. Subtract from this the heat of formation of the ionic solid that would be formed from combining these elements in the appropriate ration. 82, P. 950-952. The ground state electronic configuration of the calcium atom is [Ar] 4s2. (Na)=495 kJ/mol Bond Energy (O2) = 495 kJ/mol E.A. This energy is known as Lattice Energy (U) and its value depends upon the strength of the Ionic bond.

The nearest neighbors of Na+ are 6 Cl- ions at a distance 1r, 12 Na+ ions at a distance 2r, 8 Cl- at 3r, 6 Na+ at 4r, 24 Na+ at 5r, and so on. To correct for this, Born and Land (yes, the same Born as in the Born-Haber cycle, prolific, we know) proposed an equation to describe this repulsive energy: By adding this correction to the hard-sphere equation, differentiating it with respect to rrr, assuming that at r=r0r=r_0r=r0 the potential energy is at a minimum, rearranging for BBB, and finally substituting that back into the hard-sphere equation, you end up with the Born-Land equation: As you might expect, the Born-Land equation gives a better prediction of the lattice energy than the hard-sphere model. In order to use the Born-Haber Cycle, there are several concepts that we must understand first. Some require such high temperatures that they decompose before they can reach a melting and/or boiling point. In the case of the calcium chloride compound (CaCl2), The electronegativity value of the calcium atom = 1.0, The electronegativity value of the chlorine atom = 3.16, The electronegativity difference of the Ca-Cl bond = 2.16. Metals have very low ionization energy (I.E.) Required fields are marked *. It is an inorganic . It is this that causes ionic solids to have such high melting and boiling points.
