Atomic Structure and Bonding Theories
Zumdahl Chapters 7-9
AP Learning Objectives: The following AP topics will be covered in the textbook reading, class discussions and lab activities. Students' understanding and articulation of these topics will be tested by past AP questions on quizzes and unit test.
I. Structure of Matter (20% of AP exam)
A. Atomic Theory and atomic structure
1. Evidence for the atomic
theory
2. Atomic masses; determination
by chemical and physical means
3. Atomic number and mass
number; isotopes
4. Electron energy levels:
atomic spectra, quantum numbers, atomic orbitals
5. Periodic relationships
including atomic radii, ionization energies, electron affinities,
electronegativities
B. Chemical Bonding
1. Binding forces
a.
Types: ionic, covalent
b.
Polarity of bonds
2. Molecular Models
a.
Lewis Structures
b.
Valence bond: hybridization of orbitals, resonance, sigma and pi bonds
c.
VSEPR
3. Geometry of molecules and
ions, dipole moments
II. Descriptive Chemistry: Relationships in the periodic table: horizontal, vertical, and diagonal
