Magnesium iodide, naming

Binary Ionic Compounds Binary ionic compounds are ionic compounds that have just two different elements present. Examples are NaCl and Mgl2. When naming a binary ionic compound, name the metal first and then name the non-metal with the ending -ide. There are no prefixes used when naming binary ionic compounds. The names of the example above are sodium chloride and magnesium iodide. 

This is named by stating the name of the metai foiiowed by the name of the anion. The name of the anion is iod- foiiowed by -ide. The name of the compound is therefore magnesium iodide. 

The force of attraction between the l-i- charge on the sodium cation and the 1- charge on the chloride anion creates the ionic bond in sodium chloride. Recall that sodium chloride is the scientific name for table salt. Chemists call table salt by its scientific name because the word salt can actually be used to describe any one of thousands of different ionic compounds. Other salts that are commonly found in a laboratory include potassium chloride, magnesium oxide, and calcium iodide. 

Seawater contains many dissolved substances, mostly dissolved sodium chloride. In Chapter 4, you learned that sodium chloride is an ionic compound. Another ionic compound found dissolved in seawater is magnesium chloride. Some common ionic compounds used in everyday life are potassium chloride, a salt substitute used by people avoiding sodium for health reasons potassium iodide, added to table salt to prevent iodine deficiency and sodium fluoride, added to many toothpastes to strengthen tooth enamel. You will learn how to use the language of chemistry to name and write the formulas of ionic compounds.
