a currently-displayed structure, using the Atoms Inspector's
contextual or Actions menus (e.g., Radii > Use Default Radii). WebElements: THE periodic table on the WWW [www.webelements.com] R D Shannon and C T Prewitt (1969) Acta Cryst. Browsing an Element Table using CrystalMaker X's Preferences panel. There are several other ways ways to define radius for atoms and ions.
More specifically, potassium, which has an atomic number equal to #19#, has #19# protons in its nucleus.
However, even for
atoms of the same type, atomic radii can differ, depending
on the oxidation state, the type of bonding and - especially
important in crystals - the local coordination environment. Covalent Radii: Data given here are taken from
WebElements, copyright Mark Winter, University of Sheffield, UK.
The data were derived by the comparison of bond
lengths in over 1200 bond types in ionic, metallic, and covalent
crystals and molecules by: J C Slater (1965) Quantum Theory of Molecules and Solids. An Actions popup menu provides access to
the different Element Tables that are included with
the program; once loaded, a new Element Table becomes your
default set, ready for use with any new or imported structure. For electronic configurations, where it matters, the values given for octahedral species are low spin unless stated to be high spin.

Many organic chemists use the so-called CPK colour scheme These
colours are derived from those of plastic spacefilling
models developed by Corey, Pauling and (later improved on
by) Kultun ("CPK"). Most data here are from: "Crystal" Radii: These data are taken from Shannon &
Prewitt's (S∓P) seminal work on "physical" ionic radii, as
determined from measurements of real structures. The details are given in the element text
file after each data entry. 38:2686.
