What chemisttree said holds for most all simple molecules you could write a formula for. As they get more complicated, especially with organic ones, there's an extensive hierarchy of what goes first, how atoms are grouped together, and what name the compound has by IUPAC standards.

Which can get *really* complicated once you get deep into organic molecules, to the point where you have a method where you assign points to each atom in a molecule to decide whether the molecule has a 'clockwise' or 'anti-clockwise' configuration....
