WebThere are several other ways ways to define radius for atoms and ions. Follow the appropriate hyperlinks for literature references and definitions of each type of radius. All values of radii are given in picometres (pm). Conversion factors are: 1 pm = 1 × 10 ‑12 metre (meter) 100 pm = 1 Ångstrom. 1000 pm = 1 nanometre (nm, nanometer) WebHis studies found that crystal structures obey the following rules, now known as Pauling's Rules. Rule 1. Around every cation, a coordination polyhedron of anions forms, in which the cation-anion distance is determined by the radius sums and the coordination number is determined by the radius ratio.
