2. Understand what Electronegativity (EN) means and the trends on the Periodic Table. |
|
2. Write the chemical name from the chemical formula of a molecular cpd (called molecular formula) and visa versa. You will need to memorize the Prefix Table in Naming Molecular Compound handout.[4.6,4.7](4.6) |

3. Using the deltaEN, determine the types of bonds (i.e. covalent or "ionic" bond) between two atoms.[4.3] 4. Write the chemical name from the chemical formula of a molecular cpd (called molecular formula) and visa versa. You will need to memorize the Prefix Table in Naming Molecular Compound handout.[4.6,4.7](4.6) 5. Write Lewis Dot Structures for Elements and all species that contain covalent bonds (molecular cpds or polyatomic ions). You will need to memorize the Rule of Eight or Octet Rule. This includes resonance structures and exceeding the Rule of Eight conditions.[4.2](4.2) 6. Understand the meaning of the subscript in the chemical formula of an ionic cpd and molecular cpd.[4.6] 7. Define crystal and salt. 8. Correctly set-up and calculate One Step Mole Calculation Problems using the Mole Wheel in your folder including molar mass calculation and the sig fig rules.[5.3,5.4,5.5](5.3) 10. Memorize the seven diatomic elements (H2, N2, O2, F2, Cl2, Br2, I2). These are all gases at room temp except Br2 (a liquid) and I2 (a solid). 11. Understand how Percent Composition relates to Law of Definite Proportion and the definition of a compound.[5.4](5.4) 12. Calculate percent composition from mass information and a chemical formula.[5.4](5.4) |
