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 .
Is a metalloid or not?
There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry. The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium.
Is a metalloid a nonmetal?
The metalloids are intermediate in their properties. In their physical properties, they are more like the nonmetals , but under certain circumstances, several of them can be made to conduct electricity.
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.
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 gold a metalloid?

Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine , the rarest naturally occurring element on Earth.
Why is aluminum not a metalloid?
Re: Why aluminum not metalloid? Answer: The physical & chemical properties of aluminum are more similar to the general properties of metals . Since the energy of the valence e- in the d-orbitals are very similar to the transition metals it can have various oxidation states.
Are metalloids still metals?
A metalloid is an element that has properties that are intermediate between those of metals and nonmetals . Metalloids can also be called semimetals. ... Notice that aluminum borders the line, but it is considered to be a metal since all of its properties are like those of metals.
Is Potassium a metalloid?
Potassium is a metal . Potassium is in the fourth row in family IA on the periodic table.
Are metalloids good conductors?
Metalloids are unique because they have properties of both metals and non-metals. ... Most metalloids have a metallic lustre but are poor conductors of heat and electricity .
Why is carbon not a metalloid?
Carbon is a non-metal. It belongs to the fourteenth group or IV A group in the modern periodical table. The elements of this group have four electrons in the valence shell. ... Hence, carbon cannot form C 4 – ions so easily .
Do humans use germanium?
Germanium is a chemical element. People sometimes use it as medicine. Despite serious safety concerns, germanium is used for cancer, heart disease, hepatitis, glaucoma , and other conditions. But there is no good scientific evidence to support these or other uses.
How do humans use 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.
Is germanium found in the human body?
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. But the purported health benefits of germanium haven’t been supported by research.
Can gold be detected by a metal detector?
For instance, all metal detectors will find gold but there are different types made that are more sensitive to and specifically for gold. So, if you are solely interested in locating gold jewelry, you will want to select a detector made specifically for this purpose. Some metal detectors are water proof.
