The cation's name commonly ends in -ium note that many of the metallic elements, on the left-hand side of the periodic table, have names that end in -ium. These compounds are named by placing the name of the cation first, followed by the name of the anion. That's our goal!īinary ionic compounds contain two different types of ions (although the actual number of particles in the compound may be greater than two). With practice, you'll be able to flawlessly convert from a name to a reasonable, descriptive molecular formula.

Converting from a molecular formula to a name will help you learn how to communicate the identity of substances clearly in words-a very important problem as the diversity and complexity of known substances continues to increase! Doing the reverse, converting a name to a formula, will help you become familiar with the charges of commonly encountered ions. One nice way to gain familiarity and exposure to ionic compounds is to study the system of nomenclature used to assign unique names to them. They are often colorful when burned, and so find applications to fireworks, flares, and lighting. They may bind tightly to other charged particles, for example in environmental samples or in the human body. They conduct electricity when dissolved in water and serve as electrolytes for batteries. Ionic compounds are important for a variety of reasons. Positively charged ions are called cations and negatively charged ions are called anions. The ions are oppositely charged and are held together (in the solid phase) by electrostatic attraction.
Ionic compounds consist of two or more charged particles called ions.
