Learning Goals:
1. Be able to classify a compound as either ionic, molecular or aqueous acid from looking at its formula.
2. Be able to classify if a formula is binary or ternary in addition to above categories.
3. Know definition of cation and anion; be able to recognize monatomic and polyatomic cations & anions.
4. Be able to predict charge for ions of main group elements; write their names and formulas (example: S
would have a charge of 2-, called sulfide ion and written as S2-)
5. Using the Stock Method of naming (Roman numerals for ion charge) be able to name transition metal
cations
6. Using the Latin Method of naming (Latin name with -ous or -ic ending) be able to name transition metal
cations
7. Learn the formulas and names for the 10 polyatomic ions (carbonate, bicarbonate, hydroxide, nitrate,
nitrite, sulfate, sulfite, phosphate, phosphite, ammonium)
8. Be able to write chemical formulas and names for ionic compounds
