  1. Covalent Compounds Lewis Dot Structures & Naming

  2. 4.Turn pairs of shared e- into () Drawing Lewis Dot Structures Covalent compounds 1. Figure valence e- for each atom 2. Draw Lewis Dot Structure 3.Combine atom so each has 8 e- exception - H - needs 2e- only

  3. H H H O H O H H O H2O(covalent) + Dashes represent 2 shared e-

  4. H H H H H H C H C H H C H H H Example CH4

  5. C C O O O O Lone pair of e- O = C = O Example CO2

  6. Naming compounds - simple covalent Nonmetal farthest left 2. Other non-metal w/ “-ide” ending 3. Add prefixes- # of each element (if needed)

  7. Prefixes mono - 1 di- 2 tri- 3 tetra- 4 penta- 5 hexa- 6 hepta- 7 octa- 8 nona- 9 deca- 10

  8. Examples NO - Nitrogen monoxide NO2 -Nitrogen dioxide N2O - dinitrogen monoxide N2O5 - dinitrogen pentoxide
