1 Extra Credit Directions 1. Everything must be correct in order to receive extra credit. There is no partial extra credit. 2. Using the provided charts, you will end in one of the outlined boxes that have the rule number. That is the number that you will provide in the Rule Column. 3. Label ALL units in the molar mass column.

2 HOW TO WRITE NAMES FOR COMPOUNDS Start Covalent Compound (two nonmetals) RULE 1: Use Greek prefixes to indicate amount of each element. Do not use "mono" for the first element Ionic Compound (metal + nonmetal(s)) Is the first element hydrogen? This means it's an acid Does it have two total elements or more than two? Does it have two elements or more than two? If just has two elements, it is a BINARY IONIC COMPOUND More than two = polyatomic ion If just has two elements, it is a BINARY ACID Polyatomic ion ends with -ate (or has cyanide) Polyatomic ion ends with -ite RULE 2: Write the full name of the cation, and the anion ends in - ide RULE 3: Write the full name of the cation and full name of anion. Either cation or anion is a polyatomic ion. RULE 4: Write the word "hydro" followed by the root of the other element then "- ic acid" RULE 5: Do not write the word hydro, just use the root of the polyatomic ion with the ending: - ic acid RULE 6: Do not write the word hydro, just use the root of the polyatomic ion with the ending: - ous acid Does it have a transition metal? Does it have a transition metal? If applicable, keep "per" in the name of the acid If applicable, keep "hypo" in the name of the acid RULE 2.5: Transition metal MUST have roman numerals to indicate charge RULE 3.5: Transition metal MUST have roman numerals to indicate charge

3 HOW TO WRITE FORMULAS OF COMPOUNDS Start Covalent Compound (two nonmetals) RULE 1: The Greek prefixes indicate how many of each atom there are. Ionic Compound (metal + nonmetal(s)) Does it have the word "acid" in it? Does it have the word "hydro" or not? Binary vs polyatomic ion. Does name end in -ate or -ite? (or contain ammonium, cyanide, or hydroxide) Yes No Does name end in -ide (except cyanide and hydroxide)? It has a polyatomic ion. Look at the ending Ending: -ic acid Ending: - ous acid RULE 2: Write symbols of each atom with their charges. Use cross trick to solve for formula RULE 3: write symbols of cation and anion completely with charges. Use cross trick to solve for fomula. Use parenthesis around polyatomic ions RULE 4: It is a binary acid. It only has hydrogen and one other element. Use the charge of that element to see how many hydrogens you need That means polyatomic ion ends in -ate or has cyanide Does it begin with "per"? That means polyatomic ion ends in -ite Does it begin with "hypo" Does it have a transition metal? RULE 5: Write symbols for hydrogen and polyatomic ion. Use cross trick. RULE 6: Write symbols for hydrogen and polyatomic ion. Use cross trick RULE 2.5: The charge of the transition metal is indicated by the roman numeral. Does it have a transition metal? RULE 3.5: THe charge of the transition metal is indicated by the roman numeral.
