Quick Answer: What Element Is Cd?

Cadmium is a chemical element with symbol Cd and atomic number 48. Classified as a transition metal, Cadmium is a solid at room temperature.

What is Cd in the periodic table?

Cadmium – Element information, properties and uses | Periodic Table.

What type of metal is Cd?

Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries.

What compound is Cd?

Cadmium sulfide is the inorganic compound with the formula CdS.

Is cadmium a alkali metal?

Cadmium is a lustrous, silver-white, ductile, very malleable metal. Its surface has a bluish tinge and the metal is soft enough to be cut with a knife, but it tarnishes in air. It is soluble in acids but not in alkalis.

Is Cd an atomic element?

Cadmium is a chemical element with symbol Cd and atomic number 48. Classified as a transition metal, Cadmium is a solid at room temperature.

Why is cadmium symbol Cd?

Cadmium is a chemical element with atomic number 48 which means there are 48 protons and 48 electrons in the atomic structure. The chemical symbol for Cadmium is Cd. Cadmium is a soft, bluish-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury.

Why is cadmium toxic to humans?

According to the Agency for Toxic Substances and Disease Registry (ATSDR) suggestion; cadmium is a possible lung carcinogen in humans (41). Cadmium is absorbed through the gastrointestinal tract (GIT). Its solubility and absorption are affected by gastric and/ or intestinal pH.

What is the charge for CD?

Answer: Cadmium and all of the transition metals are the weird ones. One can have multiple oxidation states, and unfortunately, you just have to get yourself familiar through practice. Cd like Zn prefers being 2+ and sometimes can be +1.

Why are CdS yellow?

…of some economic value is cadmium sulfide, CdS. Generally produced by treating cadmium solution with a soluble sulfide, it is a bright yellow pigment known as cadmium yellow, which is used in high-grade paints and artist’s pigments because of its colour stability and resistance to sulfur and oxidation.

How many electrons are in CD?

Cadmium atoms have 48 electrons and the shell structure is 2.8. 18.18. 2.

How does a CdS cell work?

A CdS cell is a large area photo resistor, made by depositing doped cadmium sulfide on a ceramic substrate. The CdS cell resistance changes in proportion to the amount of visible light; this allows more or less voltage/current to appear at the input of an electronic switching circuit.

Why is cadmium bad for the environment?

Cadmium can accumulate in liver, kidneys and bones, which may serve as sources of exposure later in life. In the environment, cadmium is toxic to plants, animals and micro-organisms. Being a simple chemical element, cadmium is persistent – it cannot be broken down into less toxic substances in the environment.

How Does cadmium Affect the Body?

Acute inhalation exposure (high levels over a short period of time) to cadmium can result in flu-like symptoms ( chills, fever, and muscle pain ) and can damage the lungs. Chronic exposure (low level over an extended period of time) can result in kidney, bone and lung disease.

Where is cadmium most commonly found?

It is most often found in small quantities in zinc ores, such as sphalerite (ZnS). Cadmium mineral deposits are found in Colorado, Illinois, Missouri, Washington and Utah, as well as Bolivia, Guatemala, Hungary and Kazakhstan. However, almost all cadmium in use is a by-product of treating zinc, copper and lead ores.
