Term
| The main points of the valence bond approach to bonding are: (3) |
|
Definition
1. orbitals overlap to form bonds
2. Two electrons of opposite spin can be accommodated in the overlapping orbitals
-usually one is donated by each atom
3. because off orb ital overlap by the bonding electrons have a higher probability of existing in a region of space influence by both atomic nuclei. Both electrons are attracted by both nuclei |
