Metalloids
Metalloids are a elements that are somewhere between a metal and nonmetal. They can be used to form alloys, and they have a metallic appearance. They also have nonmetal properties such a being brittle.

What are metalloids in transistor radios used for?
The metalloids is combined in transistor radios to make them of high quality.
Tincture of iodine or iodine tincture is a disinfectant, it is also called weak iodine solution. Usually 2–7% elemental iodine, along with potassium iodide or sodium iodide, dissolved in a mixture of ethanol and water. It was used from 1908 in pre-operative skin preparation by surgeon Antonio Grossich.
What type of bond is made of nonmetals and metalloids?
The bonds between non metals and metalloids are covalent bonds.
Which element is not suitable to dope silicon to produce an n-type silicon?
Hydrogen, Helium, Lithium, Beryllium, Oxygen, Fluorine, Neon, Magnesium, Iron, Cobalt, Cadmium, Ruthenium, Iodine, Xenon, Iridium, Platinum, Uranium, Plutonium, Americium, and many more.
The only four elements that are suitable are easier to list: Nitrogen, Phosphorus, Arsenic, and Antimony.
What type of bonding happens to metalloids and metals and why?
• Metalloids: usually form covalent bonds with atoms of metals, nonmetals and other metalloids. They can easily take electrons from metals and lose electrons to nonmetals.
• Metalloids: usually form covalent bonds with atoms of metals, nonmetals and other metalloids. They can easily take electrons from metals and lose electrons to nonmetals.
They form because they want their valence shell to be full. Metals usually lose valence electrons because they want to stabilize their valence shell.
Metalloids depends because they have different properties of metals and non metals.
Where might you find a metalloid element used?
Metalloid, or semi metal is a term used in chemistry when classifying the chemical elements.
Is silicon a metal or a nonmetal or metalloid?
i think so it 's metalloid. if you have a better answer please change it
What are the properties of boron?
== == Some physical properties of boron are as follows:
- rough in texture
- black, white, or gray for the color
- has a small shine or luster
Most are shiny.
How do metals and nonmetals generally compare with respect to their densities?
The density of metals is greater.
Why metalloids are located between metals and nonmetals?
Metalloids are located between metals and nonmetals on the periodic table due to their unique properties that exhibit characteristics of both groups. They typically have metallic luster and can conduct electricity, but are brittle and not malleable like metals. This intermediate behavior allows them to act as semiconductors, making them valuable in various applications such as electronics. Their placement reflects the gradual transition in properties from metals to nonmetals.
yes. they are
What can metalloids can be made out of?
Metalloids are typically made out of elements that have properties intermediate between metals and nonmetals, such as silicon, boron, and germanium. These elements exhibit characteristics of both metals and nonmetals, making them important in various technological and industrial applications.
Why wasn't francium found for 80 years after the making of the periodic table?
Francium is a natural chemical element but the total quantity of francium in the earth crust is only approx. 30 g. Francium has ca. 40 isotopes and isomers but only two are natural: 221Fr (in the neptunium decay chain series) and 223Fr (in the actinium decay chain series). Artificially preparation of francium isotopes is also extremely difficult and expensive; and the chemistry and physics of isotopes was developed essentially after 1940. Supplementary, the most stable isotope of francium has a half life of only 21,8 minutes and is strongly radioactive; the half lives of the artificially prepared isotopes are more smaller.
This is sufficient reason to explain why francium was later discovered and why even today is only slightly studied.
