Is germanium reactive or stable?
Pure germanium is a hard, lustrous, gray-white, brittle metalloid. It has a diamondlike crystalline structure and it is similar in chemical and physical properties to silicon. Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid.
Are silicon and germanium reactive?
Anybody would expect that the silicon and germanium analogues of all the species listed above should be quite reactive indeed, and they’d be right. Most, however, are highly reactive species with lifetimes on the order of microseconds or less in the gas phase or in solution.
Is Group 14 highly reactive?
Comparative chemistry In the periodic table, the elements with eight electrons outermost form the group known as the noble gases (Group 18 [0]), the least reactive of the elements. The carbon group elements (Group 14), with four electrons, occupy a middle position.
What are some characteristics of germanium?
Germanium is a hard, grayish-white element, has a metallic luster but is brittle like glass. It is classified as a metalloid having the same crystal structure as diamond….Physical Properties.

Is germanium a transition metal?
Other elements sometimes included are the group 11 metals copper, silver and gold (which are usually considered to be transition metals); the group 12 metals zinc, cadmium and mercury (which are otherwise considered to be transition metals); and aluminium, germanium, arsenic, selenium, antimony, tellurium, and polonium …
Is germanium a conductor?
Pure silicon and germanium are poor conductors of electricity because their outer electrons are tied up in the covalent bonds of the diamondlike framework. They are not conductors in the metallic sense of the word, but are semiconductors.
Is the nitrogen family reactive?
The Nitrogen Family is made up of metals, metalloids, and nonmetals. It includes Nitrogen,Phosphorus,Arsenic,Antimony, and Bismuth. The Nitrogen Family is highly reactive, some more than others. The Nitrogen Family is also known as Group 15 in the periodic table.
What makes germanium unique?
Germanium is a lustrous, hard, gray-white semi-metallic element with a crystalline and brittle structure. It is a semiconductor. Germanium and the oxide are transparent to infrared radiation. Germanium also has the unusual property that (like water) it expands as it freezes.
Is silicon and germanium an insulating material?
A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way.
Is germanium a miracle cure?
Germanium bracelets- A Miracle Cure for Cancer Germanium has been explored to be one of the greatest achievements in the treatment of cancer. Its estimated daily intake is 1 mg, which works by improving the immune system of the patient, boosting the oxygen supply, thus making him feel more energetic.
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.
Is germanium harmfull to humans?
Germanium can break down your kidney tissue, causing kidney damage . In some cases, germanium can even cause chronic kidney failure and death. Due to these risks, most doctors recommend avoiding supplements that contain it.
What are the side effects of germanium?
Side effects of germanium include: Kidney damage. Anemia. Appetite loss. Nerve problems/damage. Muscle weakness/damage. Death.
