Some of these might be classified as salts. Atomic cost is the cost that an atom or group of atoms carries when it is in a molecule. All of the atomic charges in a species should add up to the charge on that species. Atomic costs are important because the cost on an atom in a molecule is its optimal cost. In a response if this charge is to be elevated or decreased, energy should be provided. Generally, chemical species that are positively charged are acidic; negatively charged are basic.
