Question | Answer |
Localized Electron Model (LE) | Electrons are localized on an atom or bond |
Formal Charge | # val. e - # bonds - # lone e |
Resonance | more than 1 valid lewis structure for molecule; lewis structure is the average of the resonance structures Compensates for defective LE model. Electrons are delocalized and move around the entire molecule |
Exceptions to the octet rule | B and Be electron deficient Period 3 and heavier atoms can exceed octet (3d orbitals) |
VSPER | -predicts geometries of molecules formed form nonmetals -designed to minimize electron repulsion |
