what is resonance? resonance refers to bonding in molecules or ions that cannot be correctly represented by a single lewis structure
what does resonance structure show? resonance structures show the different lewis structures of molecules and ions
what should you avoid when drawing resonance structures? avoid breaking a sigma bond; never exceed an octet for second-row elements; recognize and properly notate formal charges.
when drawing a resonance structure, what does the tail of the arrow show? the tail shows where the electrons are coming from, and the head shows where the electrons are going to
Do lone pairs change with every resonance structure? Resonance structures must also have the same amount of lone pairs.
Do the number of electrons change with every resonance structure? Resonance structures should have the same number of electrons, do not add or subtract any electrons
what happens to the hybridization when a resonance structure is drawn? The hybridization of the structure must stay the same
How are resonance structures stabilized? resonance structures, the electrons are able to move to help stabilize the molecule
the greater the number of covalent bonds? the greater the stability
