Chemistry 1 Review Objectives

Review Objectives

1. Distinguish the differences between an element, a compound, a solution, and a mixture

2. Identify physical and chemical changes

3. Understand the terms: homogeneous and heterogeneous

4. Understand the mass and the charge of electrons, protons, and neutrons

5. Understand the terms: Isotopes, mass number, atomic number, and their relationships

6. Understand the Dalton's Atomic Theory

7. Know the groups alkali metals, alkaline earth metals, transition metals, halogens, and noble gases under the periodic table; and know at least 3 elements under each group

8. Distinguish between metals and non-metals

9. Define ions, and state the charges of various common ions and know how to name them

10. NOMENCLATURE: Naming different types of compounds and writing their formulas

11. Know the relationship between Reactants and Products in a chemical reaction

12. Balance chemical equations, and notify the physical state symbols, i.e. (g), (l), (s)

13. Describe reactions by writing molecular equations, complete ionic equation, and net ionic equation; know the term spectator ions

14. Explain the properties of acids and bases, the formation of water, and some common strong bases/acids

15. Oxidation-Reduction Reactions

16. Classification of Reactions: precipitation reaction, double-displacement reaction, acid-base reaction, oxidation-reduction reaction, combustion reaction, synthesis and decomposition reactions

17. Understand the terms mole, Avogadro's Number, and how to calculate molar mass

18. STOICHIOMETRY: various mole problems

Notes:

This is the least that you need to know.  Do NOT just memorize before you fully understand the concepts.  Keep in mind: Practice makes better!  You should try to work on various types of practice questions at the end of each chapter.  Special attention should be paid to Nomenclature and Stoichiometry as these are the two topics most students are having trouble with.  If you have any further questions, you can book an appointment with me and we can talk it over.
