COVALENT SUBSTANCES

SIMPLE MOLECULAR SUBSTANCES

1)     The atoms within a molecule are held together by very strong covalent bonds

2)     By contrast, the forces of attraction between the molecules are very weak

3)     The result of these intermolecular forces is that melting and boiling points are very low, because the molecules are easily parted from each other

 4)     Most molecular substances are gases…
