Covalent Bond
- share electrons
to reach full shell
- Octet Rule
- needs 8 e-
- Valence Electrons
- removed
with
- Ionization Energy
- Share with other atoms
- Bond Pairs
- total # of
- Steric Number
- Lewis Structures
- Causes compounds
to have multiple
- Resonance
- Peptide Bonds
- is an example of
- bond b/w amino and carboxyl
group is stable due to resonance
- Stability
- increase stability,
increase difficulty
- Bond Breaking
- don't share with other atoms
- Lone Pairs
- total # of
- equal sharing of
electrons E<0.40
- Nonpolar
- contains
- Potential Energy
- higher chemical
potential energy
- unequal
sharing of
electrons
0.40<E<1.8
- Polar
- atoms share
electrons
because E<1.8
- Electronegativity
- transfer of electrons from low E, metal, to high E, nonmetal
- Ionic Bonds
- nonmetal gains e- to become
- Anion
- metal loses e- to become
- Cation
- transfer e- to reach full shell
