Molecular Structure & Bonding
Did You Know!
Molecules are made of fixed numbers of atoms joined together by covalent bonds, and can range from
the very small (even down to single atoms, as in the noble gases) to the very large (as in polymers,
proteins or even DNA).
Molecular substances tend to be gases, liquids or low melting point solids, because the i ntermolecular
forces of attraction are comparatively weak. You don't have to break any covalent bonds in order to
melt or boil a molecular substance.
