Lattice Energy
Wiki
Energy released when forming one mol of an ionic compound from gaseous ions
Forming
Greatest Lattice Energy
⬆️ charge
⬇️ distance
Anions are always
Bigger than neutral atoms
Biggest to smallest - neutral +
Zeff=
Atomic # - shielding electrons
It always ___ Energy to break a bond
Multiple bonds require ____ energy to break than single
Takes
More
Electronegativity
The ability of an atom in a molecule to attract electrons to itself
Most Polar
More Electronegative
⬆️
➡️
Formal Charge=
Group # - (1/2)(bonded electrons) - nonbonded electrons
_____ numbers don’t satisfy the octet rule
Odd
B violates the octet rule because
It’s too electropositive
Resonance structures exist as
The two electrons are spread out
Doesn’t exist as either structure
Bond Order =
Bonded domains
ΔH=
Σ(bonds broken) - Σ(bonds formed)
