| Question | Answer |
|---|---|
| hybridization | the mixing of different types of orbitals to produce new types of orbitals |
| formal charge (FC) formula | = valence electrons - 1/2 bonding electrons - non-bonding electrons |
| resonance | When the double bond in a Lewis structure can equally occur in more than one place. |
| pi bond | delocalised electrons from a bond formed by 2 overlapping p-orbitals (double and triple bond) |
| sigma bond | bond on axial overlap (single bond) |
| Trigonal bipyramidal angle | 90, 120 |
| Seesaw angle | <190, <120 |
| T-shaped angle | <90 |
| Octahedral angle | 90 |
| Square pyramidal angle | <90 |
| Square planar angle | 90 |
| Shape 5 bonding domains no non-bonding domains | Trigonal bipyramidal |
