<p>I'm taking AP Chem and I'm doing fairly well in my class at school and I'm pretty good at problems (stoich, titration, etc). However, we're doing Atomic Theory now (Electron config & periodic table) and I'm really confused. I'm just wondering if anyone knows how much Atomic Theory is on the AP test and how in depth it goes. Thanks!</p>
<p>I. Structure of Matter (20%)
A. Atomic theory and atomic structure
- Evidence for the atomic theory
- Atomic masses; determination by chemical and physical means
- Atomic number and mass number; isotopes
- Electron energy levels: atomic spectra, quantum numbers, atomic orbitals
- Periodic relationships including, for example, atomic radii, ionization energies,
electron affinities, oxidation states
B. Chemical bonding - Binding forces
a. Types: ionic, covalent, metallic, hydrogen bonding, van der Waals (including
London dispersion forces)
b. Relationships to states, structure, and properties of matter
c. Polarity of bonds, electronegativities - Molecular models
a. Lewis structures
b. Valence bond: hybridization of orbitals, resonance, sigma and pi bonds
c. VSEPR - Geometry of molecules and ions, structural isomerism of simple organic
molecules and coordination complexes; dipole moments of molecules; relation
of properties to structure
C. Nuclear chemistry: nuclear equations, half-lives, and radioactivity; chemical
applications</p>
