Answer 1

Answer #1

Cr is more noble than iron .

because Cr outer most electroinc configuration [Ar] 3d^5 4S^1.

here d orbital half filled . so this metal got extra stability than Iron . Fe configuration [Ar] 3d^6 4S^1. it is not as stable as Cr.

due less nobility or high reactivity of iron we have many minerals of iron on earth crust.
