Is germanium not an element?
Germanium is a chemical element with the symbol Ge and atomic number 32. Pure germanium is a semiconductor with an appearance similar to elemental silicon.
What type of element is a germanium?
Most elements are either metals or nonmetals. Germanium falls in the same group as carbon and silicon, but also as tin and lead. Germanium itself is classified as a metalloid.
What family does germanium belong to?
About the Group Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level.
Are germanium metalloids?
Germanium is metalloid, which means it has properties of both metals and nonmetals. Other metalloids on the periodic table are boron, silicon, arsenic, antimony, tellurium, and polonium, according to the Los Alamos National Laboratory.
Is germanium toxic to humans?
Germanium is not an essential element. Its acute toxicity is low. However, at least 31 reported human cases linked prolonged intake of germanium products with renal failure and even death. Signs of kidney dysfunction, kidney tubular degeneration, and germanium accumulation were observed.
Why is germanium so expensive?
Although not terribly rare, germanium is ten times more expensive than silver due to the expense of getting it to 99.999% purity, as in this sample (which happens to be the most commercially available grade). The pieces resemble broken glass in shape but have a wonderful yellow-green tinge.
What are 3 uses for germanium?
Germanium is used to manufacture rectifiers, transistors and weapons-sighting systems and used as a fluorescent material. Alloying agent. Germanium can also be used as a catalyst to produce plastics.
Is germanium safe to wear?
Inorganic (elemental) germanium is LIKELY UNSAFE. There have been more than 30 reports of kidney failure and death linked with use of these forms of germanium. It builds up in the body and can damage vital organs such as the kidneys. It can also cause anemia, muscle weakness, nerve problems, and other side effects.
How do humans use germanium?
Germanium is a chemical element that can be found in trace amounts in some ores and carbon-based materials. Some people promote it as a treatment for HIV and AIDS, cancer, and other conditions.
Is germanium harmful to humans?
What are 5 uses of germanium?
The largest use of germanium is in the semiconductor industry. When doped with small amounts of arsenic, gallium, indium, antimony or phosphorus, germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps.
Why is germanium important?
Germanium is an important semiconductor, mainly used in transistors and integrated circuits. They are often made from germanium to which small amounts of arsenic, gallium, or other metals. Germanium forms many compounds.
Is germanium the element a metal or nonmetal?
Germanium is a rare, silver-colored semiconductor metal that is used in infrared technology, fiber optic cables, and solar cells. Technically, germanium is classified as a metalloid or semi-metal. One of a group of elements that possess properties of both metals and non-metals . In its metallic form, germanium is silver in color, hard, and brittle.
What elements does germanium react with?
At room temperature, the germanium surface is passivated by the GeO 2 layer. When heated to red heat, germanium reacts with oxygen in the air, forming germanium dioxide.
What items contain germanium?
Germanium is found in all organic material, of both plant and animal origin. Tiny amounts of Germanium are found in many foods: broccoli , celery, garlic, shitake mushrooms, milk, chlorella , onions, pearl barley, rhubarb sauerkraut, tomato juice and the herbs aloe vera, comfrey , ginseng and suma.
What does the element germanium look like?
Germanium is grayish-white in color, hard, and shimmers. It is semi-metal, which is solid at room temperature. A member of the carbon group of elements, its chemical makeup is similar to that of silicon and tin .
