Either one.
This is incorrect. The correct answer would be that it is made of separate atoms because iron is an element or a pure substance. So, therefore it didn't combine with anyother atoms to form a molecule and that being said it is strictly made up of separate atoms and not molecules. Definitely not either one.
Iron is an element; a molecule of iron will only be one atom of iron
Iron refers to the element iron. Iron is a metal and does not consist of molecules.
Yes, iron is made of atoms.
No
Molecules which are in turn made up of atoms.
No. It's the other way around: molecules are made of atoms.
That depends. For the most common form of Iron (Iron-56), there are 56 grams. You may also call 6.02 X 10^23 atoms/molecules a "mole" of atoms/molecules.
Iron is a metal and does not consist of molecules. The number of atoms of iron in one mole is 6.022 x 1023.
If iron(II), then iron sulfate is FeSO4. This has a single Fe atom per molecule (or two Fe in two molecules). If you have iron(III), then iron sulfate is Fe2(SO4)3. This compound has two iron atoms per molecule (or four Fe in two molecules).

Molecules which are in turn made up of atoms.
Everything has atoms in it...
Iron, being a metal does not form molecules. Being an element it consists entirely of iron atoms.
No. It's the other way around: molecules are made of atoms.
Sugar is made of molecules, which are in turn made up of atoms.
No. Molecules are made of atoms.
That depends. For the most common form of Iron (Iron-56), there are 56 grams. You may also call 6.02 X 10^23 atoms/molecules a "mole" of atoms/molecules.
None. Iron is and element therefore it contains only atoms. Fats are made of very complex carbon based molecules.
Molecules are substances consisting two or more atoms.
Atoms existed before molecules do. Without atoms, molecules could not happen.
Yes. Everything is made from atoms. Including iron. Iron is an element as well so iron is made up of iron atoms. Iron is Fe on the periodic table.
