Ionic compounds are usually rigid, brittle, crystalline substances with flat surfaces that intersect at characteristic angles. Healed brittle fractures in effusive or combined explosive-effusive volcanic events. Rubidium oxide is the chemical compound with the formula Rb2O. Lattice energies cannot be measured directly but are obtained from a thermochemical cycle called the Born–Haber cycle, in which Hess’s law is used to calculate the lattice energy from the measured enthalpy of formation of the ionic compound, along with other thermochemical data.
