There is really no such thing as a "metal molecule" although there do exist molecules that have some metals in them. There are no molecules made entirely out of metal (since you would get a metallic bond, and hence a metal, rather than a molecule). The hemoglobin molecule is a good example of an organic molecule which also contains iron. And yes, in hemoglobin, the iron has a covalent bond.
All diatomic substances have covalent bonds even diatomic metal molecules such as sodium molecules (>2000 K).
The ionic bonds differ from covalent bonds in the following aspect: ionic bond is basically metal + non-metal while covalent bond is basically non metal and non metal.
Covalent bonds are usually between a non-metal and another non-metal. Ionic bonds are usually between a metal and a non-metal. Since gold is a metal it will make ionic bonds not covalent.
carbon are non-metal. Covalent bonds are formed between non-metal and non-metal.
No. Ionic bonds form crystals, and metallic bonds form metals or metal alloys. Only covalent bonding creates what we call a molecule.

ionic bonds are metal/non-metal while covalent bonds are non-metal/non-metal ionic bonds involve donating of electrons from one molecule to the other, whereas covalent bonds involve sharing of electrons between the 2 molecules.
Water molecules form covalent bonds, because they are non-metal compounds. If you mean the bonds within the water molecules themselves, they are Hydrogen bonds.
A non-metal and a non-metal form covalent bonds.

Covalent bonding is a type not found in metals (there mainly metal bonds or ionic bonds) In nonmetals more covalent bonding is common.
The elements that make covalent bonds are non-metal and non-metal chemicals
Atoms do not have covalent bonds, they form them. A covalent bond is typically non-metal to non-metal, and hydrogen is considered a non meteal
As a metal plutonium has metallic bonds. Salts of Pu have ionic bonds.
