Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice. Ionic radii are typically given in units of either picometers (pm) or angstroms (Å), with 1 Å = 100 pm. Typical values range from 31 pm (0.3 Å) to over 200 pm (2 Å). nottingham city council tax telephone numberhttp://abulafia.mt.ic.ac.uk/shannon/ how to shop for a used car onlineWebThe ionic radius increases for nonmetals as the effective nuclear charge decreases.
