.FCSys.Utilities.Chemistry.charge .FCSys.Utilities.Chemistry.chargeThis function returns the net
electrical charge associated with a species represented by a chemical
formula (formula). If the charge number is
not given explicitly in the formula, then it is assumed to be zero. A "+" or "-" without any immediately following digits is interpreted as
a charge of +1 or -1, respectively. If there is an error in the chemical formula,
then 0 is returned.
Example:
charge("Hg2+2") returns 2.
