Iron rusts.
When iron rusts, it forms a reddish-brown coating on the surface. This coating is a combination of iron oxide, and it can flake off, exposing more of the iron underneath to continue the rusting process.
Iron rusting is a chemical change.
It rusts. Check the "related links" if you are concerned for more information regarding the chemical reactions that take place and the different products formed when iron rusts.
False, iron atoms are converted to iron oxide
Iron is the transition metal that rusts when exposed to oxygen, forming iron oxide.

No. Iron rusts but it is not biodegradable.
Iron is oxidised when it turns to rust. The iron atoms lose electrons forming Iron(III) ions, which form a non-stoichiometric compound with oxygen and hydroxide ions and water. Rust is a much weaker substance than iron, and very crumbly, so iron loses its strength and may crumble away.
When iron rusts, it reacts with oxygen to form iron oxide. The iron atoms lose electrons and become oxidized, creating iron oxide compounds like Fe2O3 or Fe3O4. This process weakens the iron structure and causes it to flake and crumble over time.
Iron rusts.
The reducing agent when iron rusts is the iron itself. Iron atoms lose electrons to oxygen atoms in the presence of water and oxygen gas, leading to the formation of iron oxide (rust).
They are made of iron and iron rusts.
False. When iron rusts, iron atoms are not destroyed. Instead, iron atoms combine with oxygen in the presence of water to form iron oxide (rust), which causes the iron to corrode.
only iron rusts
When iron rusts, it forms a reddish-brown coating on the surface. This coating is a combination of iron oxide, and it can flake off, exposing more of the iron underneath to continue the rusting process.
Iron atoms are not destroyed when iron rusts; they undergo a chemical reaction called oxidation, forming iron oxide (rust). The atoms are rearranged to create a new compound, but the iron atoms still exist within the rust.
