I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.
NO! it is a chemical change, because the result is rust, and rust completely differs from iron, or whatever the heck the nail is made of. Rust, aka oxide, has a different set of physical and chemical properties than metal, and has a different chemical structure.
rusting a nail is a chemical change because of oxidation
Rusting is a chemical process called oxidation or oxidization. In the case of a nail, it is the combining of iron with oxygen to form an oxide of iron.
Rusting nails is not a physical change. It is a chemical change.

Physical, if you are not using any chemicals in the process it is a physical change.

Heating is a physical change.
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
Because the Iron in the nail is no longer just iron but oxidation plus iron, a physical change to the nail would be to cut it in-half.
Chemical change, oxygen binds with iron.
