| draw the Lewis dot diagram for lithium oxide |  |
| What is the name of the geometry that has ONLY 3 shared pairs of electrons? | trigonal |
| What is the name of the geometry that has 4 shared pairs of electrons | tetrahedral |
| What is the name of the geometry that has 2 shared pairs of electrons and 2 unshared pairs of electrons? | angular |
| Why is the water molecule angular and not linear? | the central atom has 2 unshared pairs of electrons which require more space and compress the shared pairs of electrons closer together |
