Iron is a chemical element; sand may be a compound or a mixture.
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).
pure substance
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
Iron sulfide
element
Iron filings are not an element. Iron filings are small pieces of iron that have been cut or shaved from a larger piece of iron. Iron itself is an element, with the chemical symbol Fe and atomic number 26.
When iron filings and sulfur powder are heated together, they undergo a chemical reaction to form iron sulfide. The iron sulfide produced is a compound that has different physical and chemical properties compared to iron or sulfur alone.
Iron could be a compound if you combined it with carbon. Then it would just be a alloy. Overall, iron is not a compound at all. It is an element.
Iron is a element, it isn't a compound
No. It is not. Iron is an element. Oxygen is an element. Iron Oxide is a compound.
Iron fillings are pure iron - until they start rusting. So their formula is Fe.
