Rusting is a chemical process when the surface of a metal becomes attacked by elements in air or water and it asorbs oxygen (or sometimes sulfur) to become a compound of it. However, many materials do not rust, because the modified surface so formed does not peel or flake-off, exposing more of it for this chemistry to repeat its action.
Thus rusting is a very chemical change (as peeling of the surface is not really defined as a physical change).

no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.

Rusting iron is it physical or chemical change?
Rusting iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This process cannot be easily reversed by physical means.
Is iron rust physical change or chemical change?
The rusting of iron is a chemical change because the iron reacts with oxygen in the air to form iron oxide. This process cannot be reversed by physical means and results in a new substance being formed.
