Naming compounds and writing

Ansu ers to Questions on Naming Compounds and Writing Formulas... 

There is a methodical way to unambiguously name compounds and write their chemical formulas. 

Skill 19.6 Demonstrate proficiency at naming compounds and writing formulas. 

In previous examples, we learned that when a metal and a nonmetal react to form an ionic compound, the metal loses one or more electrons to the nonmetal. In Chapter 6, where we learned to name compounds and write formulas, we saw that Group lA metals always form +1 cations, whereas Group 2A form +2 cations. Group 7A elements form -1 anions and Group 6A elements form -2 anions. 

Unfortunately, common names usually give no information about chemioal composition. To describe the atomic makeup of oompounds, ohemists use systematic methods for naming compounds and writing chemioal formulas. In this chapter, you will be introduced to some of the mies used to identify simple chemical compounds. 

The nomenclature of simple coordination compounds is developed in a set of rules for referring to ionic and neutral ligands, the number of each type of ligand, and the oxidation state of the metal. A number of examples of naming compounds and writing formulas are given.
