You will be introduced to naming rules, and write names and chemical formulas for ionic compounds.
After completing this tutorial, you will be able to complete the following:
Atoms lose or gain electrons to maintain stability. This results in the atom having a charge. A charged atom is known as an ion. The formation of an ionic compound occurs when two ions that are opposite in charge are bonded together. This bond represents an exchange of electrons between two elements. This is called an ionic bond.
Ionic bonds occur between metal and nonmetal substances. This is because metals have a low electronegativity and tend to release electrons. Nonmetals, on the other hand, have a higher electronegativity and tend to gain electrons. Bonds that form as a result of this are strong.
Ionic compounds are characterized as being electrically neutral when solid. They also have a crystal lattice structure. They can conduct electricity if they are dissolved in water or melted at extremely high temperatures.
Ionic compounds are named using the IUPAC stock naming system. The metal is named first with no changes to the name. If the compound is binary, the nonmetal is named second and a suffix "ide" is added to indicate that a bond has been made. An example of this is the compound BaS, which is named barium sulfide.
