How do you tell if a metal is chrome?

To determine if a metal is chrome, look for a shiny, reflective surface that is resistant to tarnishing and corrosion. Chrome typically has a mirror-like finish and feels smooth to the touch. You can also perform a magnet test; if the metal is not magnetic, it may be chrome. Additionally, a chemical test using hydrochloric acid can reveal chrome's resistance to corrosion compared to other metals.
