Lithium fluoride (LiF\text{LiF}LiF) is an ionic compound that is highly transparent to short-wavelength ultraviolet radiation, making it uniquely useful in specialized optical lenses. Despite this specialized optical characteristic, its other physical properties are typical of giant ionic structures.
Predict one physical property of lithium fluoride (other than its optical properties) that is typical of giant ionic structures.
