2
As atoms bond with eachother, they
decrease their potentialenergy
increase their potentialenergy
3
Compared with ioniccompounds, molecular compounds
are brittle
have lower melting points
are harder.
have higher boiling points
4
Bonding in molecules orions that cannot be correctly represented by a single Lewis structure is
single bonding.
resonance
double bonding
polyatomic
5
Malleability and ductilityare characteristic of substances with
covalent bonds
metallic bonds
ionic bonds
6
Metals are malleablebecause the metallic bonding
allows one plane of ions toslide past another
holds the layers of ions inrigid positions
maximizes the repulsiveforces within the metal.

As light strikes thesurface of a metal, the electrons in the electron sea
allow the light to passthrough.
fall to lower energy levels
become attached toparticular positive ions
