For the two-dimensional lattice illustrated below, ionic bonding is dominant and the nearest neighbour distance for all the ions is ro. Show that, taking into account only nearest neighbour and next nearest neighbour interactions, the interaction energy per ion u is given by: ro U=- 1.17e² 8πεoro TO I
