Title: WebStraw: Chemistry Review Anki Deck / Chemical Bonding / 1. Lewis Structures

Lewis Structures show the element} and all electrons (found either as bonded pairs or lone pairs)

Q: As the number of electrons shared within a bond increases, the bond length [...] and the bond energy
[...].
A: decreases; increases

Q: Formal charge is a [...] of electron bookkeeping that helps determine the [...].
A: theoretical method; most probable
Lewis structure

Q: Equation for Formal Charge
A: FC= Valence electrons – lone pair electrons – ½(bonding electrons)

Q: Electrically-neutral molecule, the sum of the formal charges of the individual atoms must be [...]
A: zero

Q: For an ion, the sum of the formal charges of its atoms must equal [...]
A: the overall charge on the ion

Q: Structures with lower absolute values of FC are [...] stable (lower energy) structures
A: the most

Q: Formal Charge is a measure of the extent to which [...] in the process of forming a [...].
A: an atom has gained or lost an electron; covalent bond

Q: What are resonance structures?
A: Resonance structures are two (or more) structures with the same arrangement of atoms but a different arrangement of electrons.
