Activator Explain why you put subscripts in chemical formulas.

Aqua Rules American Rules no Roman no Greek

Aqua Name Write element names and change ending of second element to –ide. Example: Na 2 O  Sodium oxide

Aqua Formulas Balance positive and negative charges, then add subscripts Example: Na 1+ O 2- Na 1+ Na 2 O It take 2 Na 1+ to balance 1 O 2-

Red Rules Roman Rules Roman numerals are the positive oxidation number for the transition metals (“the valley varies”)

Red Name Write element names and change ending of second element to –ide. Use the roman grid to find the red oxidation number and write as Roman Numeral.

Red Formulas Get oxidation number for red element from Roman Numeral, balance charges, and write subscripts. Example: Iron (III) oxide Oxidation number for Iron (III) = 3+ Fe 3+ O 2- Fe 3+ O 2- It takes 2 Fe 3+ and 3 O 2- to balance positive and negative charges  Fe 2 O 3

Green Rules Greek Rules Greek prefixes in name

Greek Prefixes Onemono Twodi Threetri Fourtetra Fivepenta Sixhexa Sevenhepta Eightocta Ninenana Tendeca

Green Name Turn subscripts into Greek prefixes in front of element names (do not use mono- on the first element). Change ending of second element to –ide. Example: CO 2  Carbon dioxide CO  Carbon monoxide

Green Formula Turn Greek prefixes into formula subscripts. Do not try to balance charges. Example: Carbon tetrachloride  CCl 4
