Atom Menu

This menu contains all atom-related properties, for example, charge, atom radicals, maps, and many more.

Menu item	Icon	Description
Stereo > R/S > Off	N/A	Removes the absolute stereo configuration from a chiral atom along with the marking wedge bond.
Stereo > R/S > R	N/A	Sets the absolute stereo configuration on a chiral atom to R, marking it with wedge bond.
Stereo > R/S > S	N/A	Sets the absolute stereo configuration on a chiral atom to S, marking it with wedge bond.
Stereo > Reaction > Off	N/A	Sets the stereo configuration of the atom not to be considered during the reaction.
Stereo > Reaction > Inversion	N/A	Sets the stereo configuration of the atom to be inverted during the reaction.
Stereo > Reaction > Retention	N/A	Sets the stereo configuration of the atom to be retained during the reaction.
Stereo > Enhanced	N/A	See Stereochemistry for details.
Charge	N/A	Allows you to change the charge of an atom between [-128, 128]. The number of implicit hydrogens will be adjusted if possible to accommodate the new charge. Valence errors will be highlighted in red.
Valence	N/A	Allows you to change the valence of an atom between [0, 8].
Radical > Off	N/A	Removes the radical designation from an atom.
Radical > Monovalent	N/A	Sets Monovalent radical center.
Radical > Divalent	N/A	Sets Divalent radical center.
Radical > Divalent Singlet	N/A	Sets Divalent radical center with singlet electronic configuration.
Radical > Divalent Triplet	N/A	Sets Divalent radical center with triplet electronic configuration.
Radical > Trivalent	N/A	Sets Trivalent radical center.
Radical > Trivalent Doublet	N/A	Sets Trivalent radical center with doublet electronic configuration.
Radical > Trivalent Quartet	N/A	Sets Trivalent radical center with quartet electronic configuration.
Isotope	N/A	Sets or changes the isotope number of the selected element, or resets the default atom (no isotope) when it is set to Off.
Map	N/A	Sets map labels/identifiers on the selected atoms that do not change while altering the molecule. They are useful when dealing with reactions, and can be saved in SMILES and MDL formats.
R-group	N/A	Changes the selected atom to an R-group label. R-groups symbolize alternative substituents.
R-group Attachment	N/A	The selected atom becomes the attachment point for the substituent.
R-group Attachment Order	N/A	Changes the order (numbering) of the attachment points.
Link Node	N/A	Specifies query structures containing rings or chains of variable size.
Periodic Table		Shows Periodic Table and query/atom property drawing window.
Edit Properties	N/A	Specifies the property of an atom.
Add S-group attachment	N/A	Creates an attachment point on the selected atom of an S-group.
Remove S-group attachment	N/A	Removes the highest-numbered attachment point from an atom of an S-group.
Label Editor		Format the atom label and replaces/overwrites any atom/atom label in a structure with a (formatted) abbreviation group, list/not list, R group, alias, or pseudo atom. For more information, see Atom Label Editor.
