Is cadmium a metal or metalloid?

metal
Cadmium is a silvery metal with a bluish tinge to its surface.

What are the characteristics of cadmium?

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.

What type of metal is cadmium?

Cadmium is grouped among the elements known as transition metals.

What is the classification of lead metal?

Lead is a chemical element with symbol Pb and atomic number 82. Classified as a post-transition metal, Lead is a solid at room temperature.

What is cadmium and its uses?

Cadmium became an important metal in the production of nickel-cadmium (Ni-Cd) rechargeable batteries and as a sacrificial corrosion-protection coating for iron and steel. Common industrial uses for cadmium today are in batteries, alloys, coatings (electroplating), solar cells, plastic stabilizers, and pigments.

What are 3 facts about cadmium?

The bluish-white metal that is known as cadmium is malleable, ductile and can easily be cut with a knife. Due to its excellence as an electrical conductor, cadmium is often used in electroplating and in batteries. Also, cadmium and solutions of its compounds are toxic and must be handled carefully.

Is cadmium heavy metal?

Cadmium, a heavy metal, is produced by refining zinc ores. Cadmium metal is practically insoluble in water but some cadmium salts are water soluble.

Is lead a metal nonmetal or metalloid?

metal
lead (Pb), a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table. Lead is very malleable, ductile, and dense and is a poor conductor of electricity.

Why is lead called a heavy metal?

The term heavy metal refers to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations. Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb).

Is cadmium highly reactive?

Chemical properties

Cadmium reacts slowly with oxygen in moist air at room temperatures, forming cadmium oxide: Cadmium does not react with water, though it reacts with most acids.

What Colour is cadmium?

silvery white
Cadmium is a moderately soft, silvery white metal with a melting point of just over 700 degrees Celsius. Cadmium compounds have been used as a source of colour since the discovery of cadmium in 1817 by the German chemist Friedrich Stromeyer.

What does cadmium do to 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.

Is cadmium a solid liquid or gas?

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

Where is cadmium found?

It is usually found as a mineral combined with other elements such as oxygen, chlorine, or sulfur. Most soil and rocks, including coal and mineral fertilizers, contain some cadmium. Cadmium is used in many products, including batteries, pigments, metal coatings, and plastics, and it is found in cigarette smoke.
