When you bend a metal spoon, you change its physical properties, but not its chemical composition. Metals are made up of atoms held together by metallic bonds, which allow the atoms to slide past each other and give metals their malleability and ductility. Bending the spoon changes its shape and causes the atoms to shift position, but it does not break the metallic bonds or change the chemical structure of the metal. However, bending the spoon repeatedly can cause it to weaken and eventually break.
