You have it backward in your question.

The chemical energy is a notion applied to molecules.
By definition, an element is a single atom, not a molecule.

Elemental copper does not have molecules. Instead it has a "formula unit", which is a single atom.
None. A water molecules contains one oxygen atom and two hydrogen atoms. Oxygen only contains oxygen.
Waters is made of molecules. Each of those molecules contains 3 atoms.
No, a H2O molecule, contains 2 hydrogen atoms and one oxygen atom - not the other way around as in the question.
It is true. A compound contains two or more different type of atoms.
