What are the chemical properties of metalloids?
Metalloids have properties that are in between metals and nonmetals. They have properties such as semiconductivity, which means they can conduct electricity under specific conditions and are used in electronic devices. Metalloids also tend to have varying degrees of metallic and nonmetallic properties, such as being brittle like nonmetals but having metallic luster.
What are some physical properties of metalloids?
Metalloids have properties that are intermediate between metals and nonmetals. Some physical properties of metalloids include being shiny or dull, brittle, and semi-conductive. They are also known to exhibit a wide range of melting points and densities.
Yes, iron is considered a transition metal. Transition metals are characterized by their partially filled d orbitals in the outermost shell of electrons, which gives them unique properties such as forming colored compounds and catalyzing reactions. Iron fits this criteria and is commonly classified as a transition metal in the periodic table.
Are most elements metals or nonmetals?
Actually in response to this answer, everything I have read clearly states that metals far out number all nonmetals, just look at the Periodic Table.
that guy is so wrong you are right :)

State of matter at room temperature metals metalloids and nonmetals?
Metals are typically solid at room temperature, with the exception of mercury, which is a liquid. Metalloids can exist in different states, but most are solid at room temperature. Nonmetals can be found in all three states of matter at room temperature: solid (such as carbon and sulfur), liquid (such as bromine), and gas (such as oxygen and nitrogen).
What are some chemical properties of tin?
Extraction of titanium
As the pure metal, titanium is mainly extracted from Rutile (TiO2) and Ilmanite (FeTiO3). In extraction, these oxides of titanium are converted in to TiCl4, then make it to react with magnesium or sodium metal in an argon atmosphere at the temperature around 1100 K, and taken as pure metal.
Reactivity
In the room temperature, titanium is a non-reactive metal, even though at higher temperatures such as 1000 K, it reacts with many non metals including nitrogen and oxygen to make various compounds.
Usage
Titanium is used to manufacture steel, when this metal is added they become harder alloys with considerably higher melting points, and it makes the steel more resistant in the process of rusting. These types of steel is used in building air crafts and space shuttles, and used in nuclear reactors, further in chemical manufacturing furnaces and steam turbines.
Oxidation numbers
+II oxidation state
There are very little number of compounds in this oxidation state. These can be prepared by heating titanium metal with Titanium(IV) oxide or chloride. Being less stable in the nature, they easily undergo oxidation.
+III oxidation state
Titanium(III) compounds shows transitional chemical characteristics, as it has a single electron in its 3d orbital. The respective hydrated ion, [Ti(H2O)6]3+ is purple in colour. In neutral medium it undergoes hydrolysis and makes [Ti(OH)(H2O)5]2+ which makes the medium basic. When continuously an alkali is added to the medium, as a result of the continuous hydrolysis, it will turn Ti2O3 which is a white precipitate.
Identically as Titanium(II) compounds, these also can as strong reducing agents by oxidizing into Titanium(IV) salts.
+IV oxidation state
This is the most stable state of the metal in natural atmosphere. As these ions contain no d-electrons, these show no transition element properties. As an example, salts of Titanium(IV) are usually white and makes colourless solutions. Also these compounds show similar behaviour to Tin(IV) compounds.
Where are the nonmetals located on the periodic table?
Towards the right. Specifically, towards the upper right.
Nonmetals are located in the upper right corner of the periodic table.

Are metalloids ionic or covalent?
Well a good way of finding out is the check the electro-negativity between a non-metal and metalloid. I know that if the electro negativity is above 1.7 than it's an ionic compound, if it's below it's covalent.
In this example I'll use silicon and sulfur.
Si--------------S
1.8 2.5
E(S-Si)=2.5-1.8=0.7
It appears that silicon and sulfur would most likely form an covalent compound.
Therefore metalloid when put with non-metals will most likely form covalent compound.
I hope this helps :)

What are the characteristics of metalloids?
Metalloids, by definition, have properties of both metals and non-metals. Although chemical and physical differences can vary throughout the group. But the two general characteristics are that metalloids often form amphoteric oxides and often behave as semiconductors. They can be shiny or dull and their shape is easily changed.
Some characteristics of metalloids include:
- Metalloids typically conduct heat and electricity better than nonmetals but not as well as metals.
- They tend to sit on the fence during chemical reactions, taking electrons from most of the metals and will lose electrons to most nonmetals
- Ionic bonding is rare, due to rule No 2. Covalent bonds are much more common.
- They are solids.
- They conduct heat and electricty.
- They insulate at low temperatures.
- They conduct at high temperatures.
- The metalloids (B, As, Ge, Sb, Te, Si, Po) can be semiconductors; also form amphoteric oxides.

What is an example of a metalloid?
An example of a metalloid is silicon. Metalloids have properties that are a mix of metals and non-metals, making them semi-conductors and useful in electronics. Silicon is commonly used in the production of computer chips and solar panels.
Where are the metalloids located on the periodic table?
The seven elements classified as metalloids are found on the border between the metals and the nonmetals, from groups 13 to 17 and periods 2 to 6.
The metalloids are B, Si, Ge, As, Sb, Te, and Po (boron, silicon, germanium, arsenic, antimony, tellurium, and polonium).
They are located to the right of the periodic table immediately to the left of the nonmetals.
-------
Polonium is generally considered a metal but the question is disputed.
going diagonal start with boron including Ge , Sb, and Po
Where are the metals found on the periodic table?
Metals are found on the left side of the periodic table. They include elements like copper, iron, and gold. Metals tend to be good conductors of heat and electricity and are typically solid at room temperature.
Where are metalloids found on the periodic table?
Metalloids are found along the staircase line on the periodic table, separating metals from nonmetals. Examples of metalloids include elements such as silicon, arsenic, and germanium. They exhibit properties of both metals and nonmetals.
Characteristics of metalloids?
Metalloids, also called semimetals, have the characteristics of both metals and non-metals. Three characterics of metalloids are insulate, conduct electricity, and its elements are Silicon and Boron.
Metalloid, or semi metal is a term used in chemistry when classifying the chemical elements. On the basis of their general physical and chemical properties, nearly every element in the periodic table can be termed either a metal or a nonmetal. However, a few elements with intermediate properties are referred to as metalloids. They are sometimes called (and confused with) semiconductors and semimetals.
The following elements are generally considered metalloids:
* Boron (B) * Silicon (Si) * Germanium (Ge) * Arsenic (As) * Antimony (Sb) * Tellurium (Te) * Polonium (Po) Inclusion of polonium is somewhat academic because all its isotopes are radioactive.
What is the definition of metalloid?
A Metalloid Is An Element Which Has Intermediate Properties Between Metals & Nonmetals ;)
A product made of or to do with metal.
A metalloid can have properties of both metals and nonmetals. Some examples of metalloids are Boron, Silicon, Germanium and Arsenic.
Why silicon is preferred over germanium in the fabrication of p-n junction diode?
Germanium diodes are more expensive than silicon ones, germanium is harder to process, germanium cannot be used to make integrated circuits (while early prototype integrated circuits were germanium the wiring between the integrated components cannot be integrated making it too expensive for production), germanium cannot operate with a junction temperature above 60C (silicon will operate up to 150C), and its reverse leakage current is greater. However! Germanium diodes have a lower forward voltage drop than silicon ones do, so they're better for some applications, like radio frequency detection.
Flex duct was designed to be used as a �Last 6 Feet� connector for drop ceiling applications. For this purpose there is nothing better. It also works great for multi radius connections over a short length (6 ft or less).
Ridged pipe is much better suited for longer, straighter runs. The pipe is much less restrictive and has a lower friction loss due to its smooth interior.
The ASHRE Design manual has great information on use of ducting materials.
Flex has become the materials of choice for ducting runs, only because the installers have become lazy and the company owners have become greedy. The installation cost is reduced because there is little or no time spent measuring and cutting duct to fit the application. Flex can be strung through rafters, over and around perlins, and comes in 25 ft lengths (shorter than most runs) reducing cuts and splices. It can also be strung too tight, smashed and bent to unreasonable restrictions and seldom if ever properly supported.
If used properly, flex is better than hot buttered toast. Done wrong, and reduced airflows, extreme temperature differentials and overall poor efficiency is the only possible outcome.
Most of the 92 naturally occurring elements are metal non metal metalloids or none of the above?
Most of the 92 naturally occurring elements can be classified as either metals or non-metals. Metalloids, also known as semi-metals, are a smaller group of elements that have properties of both metals and non-metals.
