Objectives of Molecular Cpd and One Step Mole

Essential Questions (EQ2): Are there any basic particles?
The student should be able to:(bolded number are MA Framework Standard numbers)

DO NOT HAVE TO MEMORIZE ANY POLYATOMIC IONS FOR TEST

1. Explain the difference between molecular compounds and ionic compounds (cpd) with respect to how valence electrons interact, bonding type, basic unit, name of chemical formula, and types of atoms (deltaEN) that make up each type of cpd.[4.1](4.1). Also, be able to explain metallic bond and what it is composed of.

2. Understand the meaning of the subscript in the chemical formula of an ionic cpd and molecular cpd.[4.6]

3. Memorize the seven (7) diatomic elements (H2,N2,O2,F2,Cl2,Br2, and I2).

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. Calculate Percent Composition problems.

7. Correctly set-up and calculate One Step Mole Calculation Problems (mass,#particle,volume) using the class rule for showing work including molar mass calculation (for cpds) and the sig fig rules.[5.3,5.4,5.5](5.3)
