What group is germanium in?
Group 14
Germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals.
Is germanium harmful 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.
What is germanium good for?
There have been claims that germanium may be beneficial for health, including improving the immune system, oxygen supply in the body, and destroying free radicals. According to Healthline, germanium has also been considered to be beneficial in treating allergies, asthma, arthritis, HIV/AIDS and various forms of cancer.

Germanium/Chemical series
Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin. Pure germanium is a semiconductor with an appearance similar to elemental silicon.
Is germanium man made or natural?
Organic germanium is a man-made blend of germanium, carbon, hydrogen, and oxygen. Common names include germanium-132 (Ge-132) and germanium sesquioxide.
Where is germanium used?
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.
Is germanium good for the body?
Despite serious safety concerns, germanium is used for heart and blood vessel conditions, including high blood pressure, high cholesterol, and heart disease; for eye conditions, including glaucoma and cataracts; and for liver conditions, including hepatitis and cirrhosis.
Why is germanium bad for you?
Inorganic (elemental) germanium is LIKELY UNSAFE. This includes certain compounds such as germanium oxide. 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.
How is germanium classified on the periodic table?
Germanium itself is classified as a metalloid. It’s hard at room temperature and looks metallic with a shiny silvery grey finish, but it’s a semiconductor, without some of the key properties of a metal. Germanium’s existence was predicted before anyone isolated it. This was a triumph for Dmitri Mendeleev in his construction of the periodic table.
What kind of liquid is germanium tetrahalide GeCl 4?
Under normal conditions GeI 4 is a solid, GeF 4 a gas and the others volatile liquids. For example, germanium tetrachloride, GeCl 4, is obtained as a colorless fuming liquid boiling at 83.1 °C by heating the metal with chlorine. All the tetrahalides are readily hydrolyzed to hydrated germanium dioxide.
Where can you find germanium in the earths crust?
Germanium is a fairly rare element that is found in the Earth’s crust. Although there are some minerals that contain a fair amount of germanium like germanite and argyrodite, they are too rare to be mined. The majority of germanium that is used by industry is produced as a byproduct…
Why is germanium used as an insulator in electronics?
It also is a semiconductor, which means it has electrical conductivity between an insulator and a conductor. This characteristic has led to it being used in electronics . Germanium does not react with oxygen at room temperatures, but will form germanium dioxide at higher temperatures.
