Charges of non-metal atoms are set to zero and implicit hydrogens

are added/removed to neutralize the molecule.

Charged structures with counterions are neutralized if each

individual entity can be neutralized separately.

Charged structures with counterions are not neutralized if the

total charge of the structure is zero, and the structure contains

individual entities which cannot be neutralized separately.

If the molecule cannot be neutralized by charge manipulation

and hydrogen addition/removal without violating valence rules,

it remains unchanged.

Mesomer structures with adjacent opposite charges remain intact.

Note :

The action only operates through hydrogen manipulation, i.e. adds or removes hydrogens to create a neutral compound.
