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...
