Activator Explain why you put subscripts in chemical
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 2 O It take 2 Na 1+ to balance 1 O 2 -
Red 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+ 2 O Fe 3+ 2 - It takes 2 Fe 3+ and 3 O 2 - to O Fe 3+ O 2 - balance positive and negative charges Fe 2 O 3
Green Rules • Greek prefixes in name
Greek Prefixes • • • One Two Three Four Five Six Seven Eight Nine Ten mono di tri tetra penta hexa hepta octa nana deca
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
