Cadmium is the chemical element with atomic number 48 and chemical symbol Cd. Like tin, if you bend a bar of cadmium it emits a characteristic "scream." Cadmium is a soft, bluish-white transition metal commonly used in rechargeable batteries. It is also used in pigments (red, orange, and yellow) and in low-melting alloys for solder. Despite its usefulness in a variety of applications, cadmium compounds are being phased out due to their toxicity.
