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.
List all the metalloids in the periodic?
The metalloids of the perioic table are: B, Si, Ge, As, Sb, Te, Po, and At
Which elements in the periodic table are metalloids or have semimetallic properties?
The elements that are commonly recognized as metalloids or semimetals are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te). These elements exhibit properties of both metals and nonmetals, such as being good conductors of electricity but also brittle and less malleable.
What side of the periodic table are metalloids located on?
Metalloids are located on the staircase line between the metals and nonmetals on the periodic table. They include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium. Metalloids have properties of both metals and nonmetals, making them semi-conductors and having varying degrees of electrical conductivity.
Which metalloids have symbols not based on English names?
Two metalloids with symbols not based on English names are antimony (Sb) and germanium (Ge). Their symbols are derived from their Latin names: stibium for antimony and germania for germanium.
What are the major uses of metalloids?
Metalloids are elements that have properties of both metals and nonmetals. They are often used as semiconductors meaning they can be used to conduct electricity under certain conditions. The major uses of metalloids include:
- Electronics Metalloids are used in transistors and diodes which are essential components of almost all electronic devices.

What are the similarities metals and nonmetals have in common?
Metals and nonmetals are both in the periodic table. They both have atoms in them.
What ingredients contain boron?
Foods That Contain Boron Include: Cabbage contains 145 ppm (parts per million) boron on a dry-weight basis
Dandelion contains 125 ppm boron meaning that just ten grams (just under 7 tablespoons) of dried dandelion shoots could provide more than 1 milligram of boron.
Parsley is rich in boron and it takes about 3 ounces of dried parsley to provide 3 milligrams of boron.
Apples consumed raw and with the skin contain 2.73mg of boron per kg on a fresh weight basis.
Other food sources of boron include dried fruits, grape juice, cherries, avocados and broccoli.
-----------------------------------------------------------------------------------
1. Boron is contained in fruits in vegetables.
2. The role of boron in human organism was not known today.
3. The concentration o boron in fresh foods is measured at the level of mg/kg (1-2 ppm).
Can you give examples of elements that are metalloids?
The metalloids are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium.
Which three groups of the periodic table contain the most elements classified as metalloids?
