Compound Names and Formulas

Ionic Compounds CATIONS CATIONS Na = Sodium ionNa = Sodium ion Mg = Magnesium ionMg = Magnesium ion Anions Anions F = Fluoride ionF = Fluoride ion Cl = Chloride ionCl = Chloride ion Sodium Chloride Sodium Flouride Magnesium Fluoride Magnesium Chloride *Ionic Bonds Create a Neutral Compound*

Covalent Compounds Prefix: Prefix:Mono-Di-Tri-Tetra-Penta-Hexa-Hepta-Octa-Nona-Deca The word mono, is not used for the first element The word mono, is not used for the first element Examples: Examples: N 2 O 4 = Dinitrogen TetroxideN 2 O 4 = Dinitrogen Tetroxide CH 2 O= Carbon Dihydrogen monoxideCH 2 O= Carbon Dihydrogen monoxide BF 3 = Boron TriflourideBF 3 = Boron Triflouride P 4 O 10 = Tetraphosphorus DecoxideP 4 O 10 = Tetraphosphorus Decoxide

Metallic Compounds Same as Covalent Same as Covalent EXCEPT metals not changed to ide EXCEPT metals not changed to ide

Empirical Formula Simplest formula- ratio EXAMPLE: CH2O C2H4O2 or C6H12O6 or C8H16O8 *Different compounds* MOLECULAR FORMULA Exact formula for that particular compound.
