Learning Objectives:  Name ionic and covalent compounds and derive their chemical formulas  Draw Lewis structures of simple covalent compounds In this laboratory exercise, we will learn how to derive formulas of ionic and covalent compounds and name them. We will also flame test for various metal ions and make models of simple covalent molecules. Exploration 1: Explain the following terms (Complete prior to class). Cation: loses an electron, becomes positive Anion: gains an electron...

Chemistry Final Exam (Answered) Oxidation Rules Rule 1: The oxidation number of an element in its free state = 0 (Also true for diatomic elements) -Mg=0,H2=0, C=0 Rule 2: The oxidation number of a monatomic (one-atom) ion is the same as the charge on the ion -Mg^2+=+2, Na^+=+1, O^2-=-2 Rule 3: The sum of all oxidation numbers in a neutral compound is zero. The sum of all oxidation numbers in a polyatomic (many-atom) ion is equal to the charge on the ion. Rule 4: The oxidation numb...
