Atom properties

The atom properties are exported to CDX file format the following way:

Atomic charge(tick) 
's<n>' query property except 's*'(tick)Substituents Exactly
's*' query property(tick)Free Sites '*0'
'u' query property(tick)Unsaturation
Reaction Stereo(tick) 
Enhanced Stereochemistry(tick) 
'h<n>' query property except 'h<0>'(tick)Free Sites set to implicit hydrogens on the atom minus n.
'h<0>' query property(tick)Implicit Hydrogens not allowed.
'rb<n>' query property(tick)Ring Bond Count
'H', 'X', 'R', 'r' query properties and Query Valence(tick)Written and read as user definied properties. ChemBioDraw removes them.
