Atom number, as text.

ChemDraw is extremely flexible in what it allows for atom numbers: any string is valid, and this property is not limited to numeric values. For example, not only is "2" a valid atom number, but so are 2', 2a, b, and b'.

If this property is absent:

The node does not have an atom number.
