F... — Problems And Solutions In Inorganic Chemistry

Predicting atomic size, ionization energy, or electronegativity variations. Use the core principles of effective nuclear charge ( Zeffcap Z sub e f f end-sub ) and screening constants ( ) to explain trends rather than memorizing the table.

Determining shapes and hybridization of "unusual" molecules.

Assign oxidation numbers to every atom; use the half-reaction method to ensure both mass and charge are balanced.
