  1. 7th inning stretch Draw the Lewis structure for each: • PCl3 2. SCl2 3. CS2 4. CH4

  2. 7th inning stretch Draw the Lewis structure for each: • PCl3 2. SCl2 3. CS2 4. CH4

  3. The lewis structure of water: unshared e- .. : H 2 X 1e- =2e- __ O H H O 1 X 6e- =6e- Shared e- Total 8e- - 4e- bonded 4 e- Water has 2 shared & 2 unshared pairs of e-

  4. - + What did you observe?

  5. e- move towards the protons

  6. What holds electrons in an atom?

  7. e- like protons

  8. Do electrons like each other electrons?

  9. NO

  10. - - What did you observe between the electrons?

  11. e- Repel e- move as far away from each other…..

  12. However, they do exist in pairs (remember two per e- cloud shape)

  13. V S E P R THEORY Draw the following table:
