Cadmium Cadmium is a soft, malleable, ductile, bluish-white divalent metal. It is similar in many respects to zinc but forms complex compounds. Unlike most other metals, cadmium is resistant to corrosion and as a result it is used as a protective layer when deposited on other metals.admium and its congeners are not always considered transition metals, in that they do not have partly filled d or f electron shells in the elemental or common oxidation states. The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm).

Facts About Cadmium Cadmium is a soft, bluish-white metal that can be easily cut with a knife. It is similar to zinc in many aspects. [See Periodic Table of the Elements ]. Cadmium and solutions of its compounds are toxic.Failure to take care when handling cadmium can cause exposure to dangerous fumes. Cadmium poisoning is a serious health problem that can occur from long-term exposure and work with cadmium-plating baths. Silver solder also contains cadmium and should be handled with care.

Lead Lead is a chemical element with symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and has a relatively low melting point. When freshly cut, lead is bluish-white; it tarnishes to a dull gray color when exposed to air.

Itai-itai disease Itai-itai disease (イタイイタイ病, itai-itai byō? ), (literally: ouch-ouch disease) was the first documented case of mass cadmium poisoning in the world in Toyama Prefecture, Japan in 1950. The cadmium poisoning caused softening of the bones and kidney failures.

- Cadmium toxicity occurs when a person breathes in high levels of cadmium from the air, or eats food or drinks water containing high levels of cadmium. Cadmium is a naturally occurring metal, but it is usually present in the environment as a mineral combined with other elements (eg, oxygen, chlorine, sulfur).

Cadmium chloride Although it is considered to be ionic, it has considerable covalent character to its bonding. The crystal structure of cadmium chloride (described below), composed of two-dimensional layers of ions, is a reference for describing other crystal structures. Also known are CdCl 2 .H 2 O and CdCl 2. 5H 2 O.

- Most cadmium used in the US is a byproduct of the productions of metals such as zinc, lead, and copper. When cadmium enters the air, it binds to small particles. It falls to the ground or water as rain or snow, and may contaminate fish, plants, and animals.

OSMIUM Osmium was discovered in 1804 by English chemist Smithson Tennant (1761-1815). Tennant found the new element in an ore of platinum. Osmium is a very rare element and has few commercial uses. Osmium tetroxide (OsO 4), is more widely used, however, because it is so active.verview. Osmium is an element in Group 8 (VIIIB) of the periodic table. The periodic table is a chart showing how chemical elements are related to one another. Osmium is also a member of the platinum family. This family consists of five other elements: ruthenium, rhodium, palladium, indium, and platinum.

What is Palladium? Palladium is a lustrous silvery white metal with the atomic number 46 and chemical abbreviation of Pd.It is used in electronics, jewelry, and certain other industries. Because the metal is extremely rare, palladium is considered to be a precious metal, and it can command a high price on the open market.d. As a member of the platinum group, which also includes metals like rhodium and iridium, palladium is considered a transition metal. It is one of the softer metals in the platinum group, but it retains other valuable properties that are shared by metals in this group.

What is Heart Disease? Coronary heart disease (CAD) is the most common of many types of heart disease, not only in men but also in women. It is caused by atherosclerosis, or hardening of the arteries, which occurs when plaque from cholesterol and other substances accumulate in the arteries.

- Osmium is the least abundant stable element in the earth's crust and is the densest stable element. It is found in the alloys osmiridium and iridiosmium and as an uncombined element. Osmium was first discovered by Smithson Tennant in 1803.his compound forms spontaneously when pure osmium metal is in contact with air, and is both volatile and extremely toxic, and thus the pure metal is rarely used. Osmium is, however, the most dense naturally occurring element and imparts hardness when used in metal alloys.

It's Elemental Metallic osmium is hard, brittle and very difficult to make. Powdered osmium is easier to make but emits osmium tetroxide (OsO 4) when it is exposed to the air. Unfortunately, osmium tetroxide smells bad and is very poisonous. Because of these problems, osmium is primarily used to make very hard alloys. Osmium alloys can be found in ball point pen tips, fountain pen tips, record player needles, electrical contacts and other devices where frictional wear must be minimized. Estimated Crustal Abundance: 1.5×10 -3 milligrams per kilogram.

Cadmium - Cd Cadmium is first transported to the liver through the blood. There, it is bond to proteins to form complexes that are transported to the kidneys. Cadmium accumulates in kidneys, where it damages filtering mechanisms. This causes the excretion of essential proteins and sugars from the body and further kidney damage.

These deposits cause arteries to become narrow and blocked, which restricts blood and oxygen flow to the heart muscle.

- Pure cadmium is a soft, silver-white metal found naturally in small amounts in soil. Cadmium usually combines with other things to form different compounds. Some of these compounds affect the body more than others. Cadmium does not have a definite taste or odor.Cadmium is not mined, but it is a by-product of the smelting of other metals such as zinc, lead, and copper.Cadmium is used in nickel-cadmium rechargeable batteries and for metal plating.t will explain what cadmium is, where it is found, how it can affect your health, and what you can do to prevent or reduce exposure to it. Cadmium is released into the environment from mining and metal processing operations, burning fuels, making and using phosphate fertilizers, and disposing of metal products.
