Presentation Transcript

  1. Ch 5 Covalent BondingRemember…Covalent molecules are made from 2 or more nonmetals and the electrons are “shared.”

  2. Diatomic Molecules • Gases made of two atoms of the same element. • Naming – just use the element name Hydrogen Fluorine

  3. Prefixes Used in Covalent Molecules Don’t use for first element

  4. Example

  5. TOXIC! Laughing Gas Practice HI hydrogen iodide NF3 nitrogen trifluoride SO2 sulfur dioxide N2Cl4 dinitrogen tetrachloride NO2 nitrogen dioxide N2O dinitrogen monoxide

  6. More Practice • P4S3 • I2O5 • CS2 • B2Cl4 • Tetraphosphorus trisulfide • Diiodine pentoxide • Carbon disulfide • Diboron tetrachloride

  7. Naming Covalent Molecules - just follow the name • prefixes tell what the subscripts should be of each element Examples: • Phosphorus triiodide • Chlorine tetrabromide • Tetraphosphorus hexoxide PI3 ClBr4 P4O6
