WebThe bigger the difference between the ions in a lattice, the smaller their electrostatic forces and ultimately lower the lattice energy. The atoms that are smaller have shorter interatomic distances in the ionic lattice but higher binding forces. As a result, the higher the lattice energy of ionic solid, the smaller the size of the integral ions. Web2 de fev. de 2024 · Therefore, the hard-sphere equation for lattice energy is: U=\frac {N_ {\text {A}}z^+z^-e^2 M} {4\pi\varepsilon_0r_0} U = 4πε0r0N Az +z −e2M where: N_ {\text {A}} N A — Avogadro's number; and M M — Madelung constant. Born-Landé equation While the hard-sphere model is a useful approximation, it does have some issues.
