I know that Carbon molecules can form different structures depending on how they bond with each other: graphite, diamond, graphene and fullerene. As far as I understand, graphene is just a "sheet" of carbon atoms, 1-atom thick.
Can't all atoms (not only Carbon) be arranged in such a way?
What is it that dictates the shapes of the possible structures of atoms/molecules? I.e. why are those four carbon structures famous but no one ever hears about, say, Aluminium or Oxygen?
