Not necessarily. An element is a pure substance. You may find a pure element in a molecular form, such as Cl2 gas. A diamond could be considered to be a very large, single "molecule" of carbon. The technical answer to your question is 'no', though you may say yes if you are loose with definition. I suspect the answer you want is 'no'.
No, iron is a metallic element and do not exists as molecules, macro molecules are those which contain thousands of atoms or molecules as a single unity as starch, proteins etc.
Carbon atoms. Organic molecules, such as proteins, carbohydrates, lipids, and nucleic acids, all contain carbon atoms as their central structural element. This is why life on Earth is considered carbon-based.
Iron is an element that exists as atoms, not molecules. Each iron atom has 26 protons in its nucleus, giving it its atomic number. Diatomic molecules contain two atoms of the same element bonded together, which does not apply to iron.
Most organic compounds contain the element carbon. Carbon is essential for forming the backbone of organic molecules due to its ability to form diverse and stable bonds with various other elements.
No. A Carbon atom, like all atoms, only contain Subatomic Particles. A Molecule is a chain of atoms linked together with an atomic bond.
No, organic molecules do not have to contain calcium. Organic molecules are compounds primarily composed of carbon, hydrogen, and oxygen. Calcium is an inorganic element and is not typically found in organic molecules.

Carbon
Protiens contain nitrogen
Yes
The four molecules that contain the element nitrogen are ammonia (NH3), nitric oxide (NO), nitrogen dioxide (NO2), and nitrogen gas (N2).
Thid chemical element is carbon (C).
Diatomic molecules. H2, F2, I2, O2, Br2 and so on.
No. Molecules that contain only one element are considered elements. An example is the diatomic molecule of oxygen O2.
No, iron is a metallic element and do not exists as molecules, macro molecules are those which contain thousands of atoms or molecules as a single unity as starch, proteins etc.
Yes, all organic molecules contain carbon.
It is a compound. The molecules of a compound contain more than one element.
