  1. Chemical Compounds Chemical Names

  2. Naming of Cations • Name of the element + the word ion Examples: Na+ - Mg2+ - Al3+ - Sodium ion Magnesium ion Aluminum ion ** If it’s a Transition Metal • Use a Roman numeral that represents the charge of the ion. • Example: • Cu2+ - • Fe3+ - Copper (II) ion Iron (III) ion

  3. Naming of Anions • Name of the element with an –ide ending Examples: Cl- - F- - O2- - Chloride ion Fluoride ion Oxide ion

  4. Naming Binary Ionic Compounds +2 -1 -2 +4 Find Sn Where is it located? Use Middle Name Tin (IV) Sulfide SnS2

  5. Polyatomic Ions Tightly bound groups of atoms that behave as a unit and carry a charge. Examples: Ammonium NH4+ Cyanide CN- Sulfite SO32-

  6. Writing Formulas for Ternary Ionic Compounds A. Contain a polyatomic ion B. Same rules as for binary ionic compounds. One addition – Use parenthesis if there is more than one polyatomic ion Ex: Calcium Hydroxide Ca2+ OH- CaOH2 Ca(OH)2

  7. Boron acetate B3+ C2H3O2-1 B(C2H3O2)3 Magnesium Dichromate Mg+2 Cr2O7-2 Mg2(Cr2O7)2 MgCr2O7

  8. Naming Ternary Ionic Compounds Same rules as for naming binary ionic compounds: Name the cation – Use a Roman numeral if necessary Name the anion Do not use the word “ion” in the compound name

  9. Add to your Periodic TableWrite the two charges in the element’s box. Hg +1 & +2 Nickel +2 & +3 Gold +1 & +3

  10. Rules for Naming Covalent Compounds 1. Prefixes are used to show how many atoms of each element are present in the compound Prefixes used for Naming Binary Covalent Compounds

  11. 2. Second element is written with an –ide ending. ***All binary compounds, both ionic and covalent end in –ide. 3. The vowel at the end of the prefix is dropped when the name of the element begins with the same vowel. Example: monoxide, not monooxide Rules for Naming Covalent Compounds

  12. 4. Mono is omitted if there is just a single atom on the first element in the name. Example: carbon dioxide not monocarbon dioxide Rules for Naming Covalent Compounds
