OAE Chemistry study plan

Draw and label Bohr and quantum mechanical models of the atom, then write the full and condensed electron configuration for 20 assigned elements without notes

Rank the major subatomic discoveries (electron, nucleus, proton, neutron) by experiment and state the specific observation that forced each revision of the model

Differentiate atomic number, mass number, isotopes, and average atomic mass, and calculate weighted average atomic mass from isotope abundances for 10 practice sets

Distinguish a hypothesis, law, and theory using three chemistry examples, and identify the independent, dependent, and controlled variables in four described experiments

Explain periodic trends in atomic radius, ionization energy, electron affinity, and electronegativity in terms of effective nuclear charge and shielding, then predict relative values for 12 element pairs

Write the electron configuration and identify the valence shell for main-group and first-row transition elements, including common exceptions such as chromium and copper

Classify bonds as ionic, polar covalent, or nonpolar covalent using electronegativity differences, and rank five bonds by polarity

Connect periodic position to the formulas of common ions and to the typical charges of group 1, 2, 16, and 17 elements

Draw Lewis structures, including resonance forms and formal charges, for 15 molecules and polyatomic ions such as nitrate, sulfate, and carbonate

Predict molecular geometry and bond angles using VSEPR theory for 12 species, and identify each as polar or nonpolar from the vector sum of bond dipoles

Identify the hybridization of the central atom in 10 species and relate it to sigma and pi bonding and to the observed geometry

Explain how intermolecular forces (hydrogen bonding, dipole-dipole, London dispersion) arise from molecular structure and rank five substances by expected boiling point

Name and write formulas for ionic and covalent compounds, including those with polyatomic ions and transition metals requiring Roman numerals, for 30 items

Balance 15 chemical equations, including combustion and double-replacement reactions, and classify each reaction type

Predict products of precipitation reactions using solubility rules and write complete and net ionic equations for eight cases

Convert among moles, mass, particles, and gas volume at standard conditions for 15 calculation problems
