Which of the following elements would be expected to resemble germanium Ge most closely in chemical properties? arsenic (As) Explanation: Elements with similar chemical propertiesare arranged in the same group or verticalcolumn. Thus Germanium (Ge) would beexpected to have similar properties to silicon(Si).
What element is most similar to germanium?
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.
What elements have similar properties as germanium?
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 .
What element does germanium belong to?
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.

Why germanium is called a metalloid?
1. Germanium is shiny like metals but brittle like non-metal. It shows some of the properties like metal and some like non-metals. Most important it behaves as semi-conductor like Silicon hence like silicon it is considered as metalloid.
Is germanium a transition element?
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 good conductor of electricity?
Pure silicon and germanium are poor conductors of electricity because their outer electrons are tied up in the covalent bonds of the diamondlike framework. ... These atoms are larger and hold their electrons less tightly. They are not conductors in the metallic sense of the word, but are semiconductors.
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 Si a metal?
silicon (Si), a nonmetallic chemical element in the carbon family (Group 14 [IVa] of the periodic table).

Is germanium found in the human body?
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.
What are the benefits of germanium?
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 are Silicons properties?
Silicon is the most abundant electropositive element in The Earth's crust. It's a metalloid with a marked metallic luster and very brittle . It is usually tetravalent in its compounds, although sometimes its bivalent, and it's purely electropositive in its chemical behaviour.
