- 7.13 Figure 7-2 depicts the interactions of an ion with its first nearest neighbors, second nearest neighbors, and third nearest neighbors in a lattice, (a) Would the interactions with the fourth nearest neighbors be attractive or repulsive? (b) Based on Coulomb's law, how would the relative sizes of the terms compare if the potential energy were expressed as V=V1st+V2nd+V3rd+V4th ?arrow_forwardPredict the trend in lattice energy, from least negative to most negative, for the following compounds based on the ion charges and ionic radii; LiI, LiF, CaO, RbI.arrow_forwardWhat is electronegative radiation? Give some examples of such radiation. Explain what the wavelength ( ) and frequency (v) of electronegative radiation represent. Sketch a representation of a wave and indicate on your drawing one wavelength of the wave. At what speed does electromagnetic radiation move through space? How is this speed related to and v?arrow_forward
