the first 10 alkanes (methane (CH4), ethane (C2H6), propane (C3H8), etc.
saturated vs unsaturated hydrocarbons
Naming binary covalent compounds
isomers
polarity of bonds (electronegativity differences)
polarity of molecules, and symmetry
how water dissolves salts
the three types of bonds
alloys
the seven polyatomic ions to memorize: ammonium (NH4+), hydroxide (OH-), etc. (see the back of the pink PPT packet)
