Germanium is a chemical element with symbol Ge and atomic number 32. Classified as a metalloid, Germanium is a solid at room temperature .
Does germanium occur in Free State?
We will call it a combined state element as silicon exists as silica as well as silicate. Similarly, germanium and tin are metals that occur in the combined state , in nature. But carbon is an exception here. Carbon is such an element that exists both in free state and combined state.

What gas is germanium found in?
Germanium is located in the middle of the carbon family , which is Group 14 (IVA) in the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. Carbon and silicon are above germanium and tin and lead are below it.
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.
What is germanium an example of?
The Germanium element is not doped with any impurities. Hence, it is an intrinsic semiconductor .So, Germanium is an example of an intrinsic semiconductor.
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 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.
Is germanium shiny or dull?
Germanium atoms have 32 electrons and 32 protons with 4 valence electrons in the outer shell. Under standard conditions Germanium is a hard, shiny, silvery-gray solid that is very brittle.
Is germanium magnetic?
Abstract. The magnetic susceptibility of highly doped germanium has been measured between 300°K and 1.3°K . The contribution of the carriers to the susceptibility has been derived from the data.
Does germanium sink or float?
Germanium is stable in air and water , and is unaffected by alkalis and acids, except nitric acid. 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 heavy metal?
Environmental effects of Germanium
As a heavy metal it is considered to have some negative impact in aquatic ecosystems.
Does germanium react with oxygen?
Reactions: Germanium. The thin oxide layer renders germanium more or less inert to water. The surface of lumps of germanium is protected by a very thin layer of germanium dioxide. At red heat, germanium reacts with oxygen in air to from germanium dioxide.
