Properties of Cadmium (Cd)
Cadmium is a chemical element with the symbol (Cd) and atomic number 48. It is a soft, bluish-white metal that is commonly found in zinc ores. Cadmium is often used in various industrial applications, including the production of batteries, pigments, and coatings. However, it is considered a toxic metal and poses environmental and health risks.
