First of all we will introduce to Cadmium (Cd). What is cadmium? Cadmium is include in heavy metals which are toxic to human, Animals and plants. Cd have 48 atomic number with atomic Mass 112.411 u. Its Melting point is 321.1°C(609.9°F).
If you want to see it in periodic Table then Go to group#12>Then period#5 and then in d-block.
Any metal which density is greater than 5mg/cm3 is called heavy metal. cadmium is member of this group.
Cadmium, in its purest form, is a soft silver-white metal that is found naturally in the earth’s crust. However, the most common forms of cadmium found in the environment exist in combinations with other elements. For example, cadmium oxide (a mixture of cadmium and oxygen), cadmium chloride (a combination of cadmium and chlorine), and cadmium sulfide (a mixture of cadmium and sulfur) are commonly found in the environment. Cadmium doesn’t have a distinct taste or smell.
Uses of Cd:
Most cadmium used in this country is obtained as a by-product (formed while making something else) from smelting (melting) zinc, lead, or copper ores. The cadmium by-product is mostly used in metal plating and to make pigments, batteries, and plastics.
Effects of Cd:
Cadmium is also an environmental hazard. Human exposure is primarily from fossil fuel combustion, nonferrous metals production, phosphate fertilizers, iron and steel production, cement production and related activities, natural sources, and municipal solid waste incineration. root crops, vegetables and Bread also contribute to the cadmium in modern populations.
