Empirical, molecular, and structural formulas. A polyatomic ion, also known as a molecular ion, is a charged species (ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered as acting as a single unit in the context of acid and base chemistry or in the formation of salts. Ions in one molecule = 1 Na+ + 1 Cl-= 2 ions. The thing that I found most unique, however, was the fact that it sorted the ions by their chemical formula, rather than by charge or by name. Therefore if the total is an odd #, the charge of the ion is 1- (phosphate is the only 3- you need to know). Thus it is different from monatomic ions, which contain only one atom. Polyatomic Ions. Note that polyatomic ions don’t break apart in solution, so be sure to familiarize yourself with the common ones. Chlorine has 17 electrons (a charge of -17) and 17 protons (a charge of +17), so the overall charge is zero. The resultant dipole is shown in color. Given: cation and anion, amount, and internuclear distance. So you need two iron ions, (3 * 2 = 6), Fe 2, and three chromate ions, (2 * 3 = 6), (CrO 4) 3, to make a neutral compound.
