Pre-lab activity (10 mins)
- 1) give each student a balloon...inflate to equal size...these represent electron domains.
- 2) tie two balloons together to make a 2-electron domain system...linear.
- 3) combine together a double and single to make a 3-electron domain system...trigonal planar.
- 4) combine together 2 sets of doubles to get a 4-electron domain system...tetrahedral.
- 5) combine together a double and triple to get a 5-electron system...trigonal bipyrimidal.
- 6) combine together a double and a tetra to get a 6-electron system...octahedral.
- 7) combine together other sets to get expanded octet...
