Presentation Transcript

  1. Covalent Compounds • These compounds are formed when atoms “share” electrons in order to become stable. • Usually formed between 2 or more non-metals.

  2. Covalent Compounds • Exist in solid, liquid, and gas forms at room temperature. • Normally do not conduct electricity. [http://universe-review.ca/I13-14-sulfur.jpg]

  3. Covalent Compound Names • Example: CO2 • Carbon Dioxide • Use prefixes (pg. 593) to show how many atoms there are. [http://cwx.prenhall.com/bookbind/pubbooks/mcmurry2/chapter2/medialib/TB02_002.JPG]

  4. Covalent Compound Names • A couple “other” rules…. • Never put the prefix “mono-” on the 1st element in the name. • Always end the compound name with –ide.

  5. Covalent Compound Names • Example: NCl3 • Nitrogen Trichloride • Example: P2O5 • Diphosphorus Pentoxide

  6. Covalent Compound Formulas • Example: Dinitrogen Tetrasulfide • N2S4 • Use the prefixes in the names to determine the subscripts in the formula • Example: Carbon Monoxide • CO
