Initially shown: Jmol's default Van der Waals radius and color scheme
  
Single radius:

Ionic with charge

All radii:   (rotate the model using the mouse)
-4, -3, -2, -1, uncharged, +1, +2, +3, +4, +5, +6, +7, Van der Waals
  • for
  • only for elements in period
  • only for elements in group
Coloring schemes:
metal, nonmetal, metalloid.
main group metal, transition metal, main group nonmetal, metalloid, inner transition metal.
Singular, instructive views:
Display atom size proportional to relative abundance in humans (dry weight).
Pattern of ionization along the groups.
Only elements included in PDB or NDB.
