Naming ionic compounds: Name the cation then the anion. Organic compounds containing substituents from Group C are named following this sequence of steps, as indicated on the examples below: •Step 1. The name of a monatomic cation is simply the name of the element followed by the word ion.Thus, Na + is the sodium ion, Al 3 + is the aluminum ion, Ca 2 + is the calcium ion, and so forth.. We have seen that some elements lose different numbers of electrons, producing ions of different charges (Figure 3.3). The following guidelines for organic nomenclature are based on the def A molecular compound is a group of atoms held together by a covalent bond.
