The ions are atoms that have gained one or more electrons (known as anions, which are negatively charged) and atoms that have lost one or more electrons (known as cations, which are positively charged). [16], In humans, valeric acid is a minor product[17] of the gut microbiome and can also be produced by metabolism of its esters found in food. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Polyatomic ions are covalent units (molecules) where the total number of protons \(\neq\) to the total number of electrons and they were introduced in section 2.6.4.2.

Upper Saddle River: Pearson Prentice Hall, 2007, Nomenclature of Inorganic Chemistry, Recommendations 1990, Oxford:Blackwell Scientific Publications. If the compound is ionic, we use the principle of charge neutrality to name the compound. Consider stearic acid, a type of lipid known as a fatty acid. First, we must establish this a molecular compound before we use prefixes.

If it is an acid, we base it's name on the ionic compound it would form if hydrogen could be a cation. You should contact him if you have any concerns.

Ionic Compounds When an element composed of atoms that readily lose electrons (a metal) reacts with an element composed of atoms that readily gain electrons (a nonmetal), a transfer of electrons usually occurs, producing ions.
