Charges that follow other repeating units are distributed among those
units.
Charges may be superscripted.
Multiple charges are recognized appropriately.
Charges may have repeat counts as long as both the charge and the
repeat count are superscripted.
A “floating” charge placed with the Chemical Symbols Tool is assigned to
the nearest atom. If no atom is within the distance set as the Fixed Length,
the charge is ignored and not assigned to any atom.
A “floating” charge placed within a delocalized system is recognized by the
Analyze Structure function, but is discarded when saved to formats that
require all charges to be associated with specific atoms.
Isotopes and elements
By default, all isotopes are recognized in the full Table of the Elements. This data is provided by CRC Press, Inc. Iso-
topes are defined in the Isotopes Table file. You can edit this file in any text editor to add new isotopes.
A super-scripted number before the element symbol indicates isotope
numbers.
