The 7 elements that exist in nature as diatomic molecules are ____, ____, ____, ____, ____, ____, and ____. Ionic Compounds (section 3.5) Ionic Compounds are composed of _____________ and ___________ bonded together by ________________. A cation is a ______________ charged ion. An anion is a __________________ charged ion. The basic unit of an ionic compound is the ______________________________. How are formula units different from molecules? When writing the chemical formula of an ionic compound, the following rules apply: 1. Ionic compounds always contain a ______________ and a ________________. 2. The sum of the charges of the ______________ must always equal to sum of the charges of the _______________. 3. The chemical formula reflects the ___________ ____________ _____________ ratio of ions. When naming ionic compounds, the following rule applies: NAME OF CATION + NAME OF ANION What is the difference between a fixed‐charge metal and a variable‐charge metal? Molecular Compounds (section 3.6) Molecular Compounds are composed of 2 or more _________________ bonded together by _____________________. A Covalent Bond is _______________________________________. The basic units of molecular compounds are _____________________. When naming binary molecular compounds, use the following rule: and the following prefixes: mono = ____ di = ____ Acids tri = ____ tetra = ____ penta = ____ hexa = ____ hepta = ____ octa = ____ nona = ____ deca = ____ Acids are molecular compounds that release ___________________ when dissolved in water. An acid that is composed of only hydrogen and a nonmetal is called a ___________________ acid. An acid that contains hydrogen and an oxyanion is called an ___________________ acid. An oxyanion is __________________________________. When naming binary acids, use the following rule: 2 When naming oxyacids, use the following rules: If the anion’s name ends in “‐ate” then the acid’s name is: If the anion’s name ends in “‐ite” then the acid’s name is: End of Chapter Practice Problems Tro First edition: #29, 37, 39, 43, 49, 51, 53, 55 Tro Second Edition: #29, 37, 41, 43, 47, 49, 51, 53 answers are located in Appendix III of the textbook Take the Quiz on Blackboard 3 ...
