Day 11 skills review

  • Due No Due Date
  • Points None

DAY 11, Terms to know:

Sections 5.5, 6.1-6.3: covalent bonding, molecule, law of definite proportions, diatomic molecules, heteronuclear, homonuclear, polyatomic molecules, molecular formula, allotropes, structural formula, electronegativity, octet rule, lone pairs, Lewis structure, single bond, double bond, triple bond, bond length, bond energy

DAY 11, Specific outcomes and skills that may be tested on exam 2:

Sections 5.5, 6.1-6.3

  • Given a structural formula, be able to give a corresponding molecular formula
  • Given a molecular or structural formula, be able to determine the formula
  • Given a formula, be able to predict whether a substance is likely bonded by ionic bonds, covalent bonds, or both
  • Given a formula, be able to predict which atoms present are bonded through ionic bonds and which atoms are bonded through covalent bonds
  • Be able to explain why some bonds are shorter and stronger than others
  • Be able to rank relative electronegativities and explain WHY some atoms are more electronegative than others
  • Given a molecular formula, be able to draw a reasonable Lewis structure obeying octets and minimizing formal charge where possible

Complete these problems outside of class until you are confident you have learned the SKILLS in this section outlined on the study guide and we will review some of them next class period.  5.41  5.43  5.49  5.101  5.103  5.107  5.109  5.115  5.121  6.23  6.25  6.67  6.81  6.83
