Objectives Of Molecular Cpd And Mole Concept - Revised 2009

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. ( NOT for 2019-2020 Honors student)

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) (Not for 2019-2020 Honors students)

8. Correctly set-up and calculate One Step or Two Step Mole Calculation Problems using the Mole Wheel in your folder including molar mass calculation and the sig fig rules.[5.3,5.4](5.3)( 2019-2020 Honors student NEED TO Know)


9.Understand how to calculate the number of mole of a solute in a solution and visa versa (called Molarity calculations). Also Molarity calculations make another "spoke" on the Mole Wheel. ( 2019-2020 Honors student NEED TO Know)
10. Need to be able to determine which of three type of bonds (single, double and triple bond) has the longest/shortest bond length and/or bond energy and reason why.( 2019-2020 Honors student NEED TO Know)
