Ions formula

WebThe chemical formula of the carbonate anion is CO 3. The magnitude of the negative charge held by it is 2. Therefore, the effective charge held by the ion is -2. The … When writing the chemical formula for an ion, its net charge is written in superscript immediately after the chemical structure for the molecule/atom. The net charge is written with the magnitude before the sign; that is, a doubly charged cation is indicated as 2+ instead of +2. However, the magnitude of the charge is omitted for singly charged molecules/atoms; for example, the sodium cation is indicated as Na and not Na .
