SUMMARY
The common atomic radii used for drawing chemical pictures primarily include half the covalent radii for ball-and-stick models, as noted by various users in the discussion. While there are no strict rules governing these representations, consistency is key. Many software programs adopt similar conventions, with "spacefill" models typically utilizing full covalent radii or slightly larger. The discussion emphasizes that these visual representations serve more for structural illustration rather than precise scientific measurement.
