WebThis will be looked at in more detail in a later discussion of lattice energies. Although they are hard, they also tend to be brittle, and they shatter rather than bend. Ionic solids do … WebOn the atomic level, the kinetic energy of the atoms has increased which means the atoms are moving faster. However, in a crystalline solid, the atomic movement is limited to vibration around stable lattice positions. As the temperature increases, the atoms vibrate at a greater amplitude and move farther from their stable lattice positions. carli osika instagram
