Charges

---

Charges may be created as part of a textual atom label or with the appropriate symbol from the Chemical Symbols Palette. Charges are always assigned to a specific element in the atom label, whose acceptable valences become those of the similar isoelectronic neutral element.

	A charge following an element is assigned to that element.
	A charge that does not follow an element is assigned to the next element.
	Charges that follow a monovalent element with a repeat count are assigned to the element before that element.
	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.
