Iron atoms.
Iron, being a metal does not form molecules. Being an element it consists entirely of iron atoms.
compoundIf the iron fillings are pure, they contain only one type of atom (all the atoms have the same number of protons). Thus, the filings would be a sample of the element iron. If the filings are rusty, then they would contain compounds (iron oxides).
There is 1 Iron atom and 2 oxogen atoms in Iron rust.
They are the same. Iron is a a chemical element. It may be in different states, but iron atoms are the same no matter where in the universe they are. The same applies to any other element.
Atoms of solid iron would not have lost electrons to any other element. They are shared with the de-localized electron cloud but the oxidation state is 0. That being the case, there would be no charge. It is a free element. (No joke, a free element has no charge.) If iron were to form a compound it would typically lose two or three electrons to the anion.
The chemical symbol of an element doesn't depend on the number of atoms.
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.
Yes, atoms of any element contain only that element. It is impossible to have an impure atom.

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.

Iron is an element so it is made up only from iron atoms.

There are no iron atoms in oxygen. Oxygen is an element in itself so it can not be complicated by another element unless it becomes a molecule of something else. Usually iron that has been mixed with oxygen can be form an iron oxide.
