Atom properties dialog
In the Atom properties dialog you can set values to atoms.
Atomic charges, isotopes, radicals, enhanced stereo specifications, atom maps, aliases can be set in the Basic Tab and query properties in the Advanced Panel.
Atom properties dialog window is available from the pop-up menu after a right-click on the atom.
Set atom properties for several atoms at once
In the dialog only the properties which are permitted for every selected atom type are available.
If the selected atoms have attached previously defined properties, you can delete them by inactivating their input field via the "Padlock" icon.
The appearance of this dialog depends on the context. You can see the summary of the available properties below:

Basic Tab
Possible values
Atom: the chemical symbol of the element (the atom number appears automatically next to the text field).
In case of hydrogen isotopes (deuterium and tritium), their specific atomic symbols (D and T) can be used as well.
Alias: a text (a label to an atom) Please, note that the other properties (except query atom properties) will be hidden, however this information is preserved.
Isotope: a positive integer
Charge: (+) or ( - ), and an integer (other numbers will be rounded to an integer)
Radical: none, monovalent
Ehanced stereo: Off (default), Absolute, And, Or. In the latter two cases a number should accompany the identifier. If you leave the number field empty, number 1 will be associated with the group identifier automatically.
Map: integer
