Determine crystal structure of ionic compound
WebAn ionic crystal consists of ions bound together by electrostatic attraction. The arrangement of ions in a regular, geometric structure is called a crystal lattice. Examples of such crystals are the alkali halides, which include: other combinations of sodium, cesium, rubidium, or lithium ions with fluoride, bromide, chloride or iodide ions.
