What it is Filled
The chemical element with atomic number forty-eight, a soft, bluish-white post-transition metal chemically similar to zinc, obtained mainly as a by-product of zinc refining, with many isotopes, and used in nickel-cadmium batteries, pigments, coatings, solders and as a neutron absorber in nuclear reactors; cadmium and its compounds are toxic and carcinogenic, accumulate in the body and environment, and are restricted by regulations on products, emissions and food, all described here with attribution to authorities.
Why it exists Filled
