》Metal + Oxygen → Metal Oxide《

$\large\mathtt{\underline{\underline{\red{Additional \: Info:-}}}}$

When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is:

Metal + Oxygen → Metal Oxide.

Rust is a form of iron oxide and it forms slowly when iron is exposed to air. Iron can be transformed to steel (an alloy), which is more resistant to rust.
