  1. Formula to Name XY Xray Yellow Starts with H Starts with Non-Metal Starts with Metal yes yes yes Compound is an ACID Compound is COVALENT Compound is IONIC Hydro + root + -ic acid Is OXYGEN present? Don’t use mono on 1st element 1st element- Change subscript into prefix then write element no 1) Write the name of the 1st element yes yes if anion is an ELEMENT if anion is a POLYATOMIC ION 2nd element- change subscript into prefix, write element, change ending to -ide If polyatomic ion ends in -ite: Root + -ous Acid If polyatomic ion ends in -ate: Root + -ic Acid NO POLYATOMICS IN COVALENT FORMULAS 2) Write the name of the 2nd element, change the ending to -ide 2) Write the name of the polyatomic ion If 1st element is a transition metal Do reverse criss-cross to determine charge, use a Roman numeral after the cation Pre-fixes mono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nona-9 deca-10

  2. Name to Formula Xray Yellow XY Is 1st element a metal? Is compound an Acid? Does name have a prefix or start with a non-metal? yes yes yes Compound is IONIC Compound is an ACID Compound is COVALENT Is there a Roman numeral? Does name start with hydro-? Write elements Change prefixes into subscripts DO NOT REDUCE DO NOT CRISS-CROSS yes no yes Roman numeral tells you the charge Write symbol and charge for H and element Do Criss-cross Write symbol and charge for cation and anion Do criss-cross If root ends in -ic: use -ate polyatomic ion Write symbol and charge for H and polyatomic ion Do Criss-cross If root ends in -ous: use -ite polyatomic ion -ide = element Pre-fixes mono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nona-9 deca-10 -ite -ate = polyatomic ion

  3. Ionic Practice
