Web1 de jan. de 2024 · Early attempts to measure ionic radii include that of Landé who measured the ionic radius of iodine in LiI by assuming that the lithium ions are so much smaller than the iodide ions that the lithium fits into holes within the crystal lattice, allowing the iodide ions to touch.On this basis the iodide ion was deduced to be 214 pm. This … Web21 de mar. de 2024 · The atomic size of each element, described by the ionic radius, is one category of “material genes” and can facilitate our understanding of atomic arrangements in compounds.
