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.
500 Questions
Most of the 92 naturally occurring elements are metal non metal metalloids or none of the above?
Asked by Wiki User
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?
Asked by Wiki User
The metalloids in the periodic table are boron, silicon, germanium, arsenic, antimony, and tellurium.
Which elements in the periodic table are metalloids or have semimetallic properties?
Asked by Wiki User
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?
Asked by Wiki User
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?
Asked by Wiki User
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.
Is mercury a metal or metalloid?
Asked by Wiki User
Symbol: Hg
Atomic Weight: 200.59
Discovery: Known to the ancient Hindus and Chinese. Mercury has been found in Egyptian tombs dating to 1500 B.C.
Electron Configuration: [Xe] 4f14 5d10 6s2
Word Origin: from the Planet Mercury; Hg is the symbol for Hydrargyrum, which means liquid silver
Properties: Mercury has a melting point of -38.842°C, boiling point of 356.58°C, specific gravity of 13.546 (20°C), and a valence of 1 or 2. Mercury is one of the few elements that is liquid at ordinary room temperatures. Mercury is a heavy, silvery-white metal. It is a relatively poor conductor of heat, but a fair conductor of electricity. Mercury readily forms alloys with other metals, called amalgams. An electrical discharge will cause mercury to combine with the noble gases argon, krypton, neon, and xenon. Mercury and its compounds are highly poisonous. Mercury is readily absorbed across unbroken skin or though the respiratory or gatroinstentinal tract. It acts as a cumulative poison. Mercury is very volatile in air. When room temperature air (20°C) is saturated with mercury vapor, the concentration greatly exceeds the toxic limit. The concentration, and thus the danger, increases at higher temperatures.
Uses: Mercury is amalgamated with gold to facilitate the recovery of gold from its ores. Mercury is used to make thermometers, diffusion pumps, barometers, mercury vapor lamps, mercury switches, pesticides, batteries, dental preparations, antifouling paints, pigments, and catalysts. Many of the salts and organic mercury compounds are important.
Sources: Mercury rarely occurs free in nature. It's chief ore is cinnabar, HgS. Mercury is obtained from cinnabar by heating the cinnabar in air and condensing the vapor.

Are metalloids metals non metals the same?
Asked by Wiki User
They are in between the metals and non metals
Do metalloids react with acid?
Asked by Wiki User
no because metalloids behaves like non metals during chemical reaction.
What are the major uses of metalloids?
Asked by Dakotagentry
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.
- Solar Cells Metalloids such as silicon are used in solar cells to capture and convert solar energy into electricity.
- Aerospace Metalloids are used in the aerospace industry for various purposes including wiring and fuel systems.
- Medicine Metalloids can be used to create medical implants and prosthetics as well as drug delivery systems.
- Industrial Metalloids are used in the production of various industrial products such as steel aluminum and other alloys.
Metalloids are also used in the production of optical lenses and as a catalyst in chemical reactions. These elements are essential to many industries and have numerous uses in modern society.
What are the similarities metals and nonmetals have in common?
Asked by Wiki User
Metals and nonmetals are both in the periodic table. They both have atoms in them.
Are metalloids ionic or covalent?
Asked by Wiki User
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 :)

Is chlorine classified as a metalloid?
Asked by Wiki User
Chlorine is not a metalloid. It is a non metal.
Do metalloids have high melting points?
Asked by Wiki User
It varies on which metalloid you are talking about but in general they have low melting points
How many metalloids periodic table?
Asked by Wiki User
There are 7 metalloids on the Periodic Table of Elements:
- Boron (B)
- Silicon (Si)
- Germanium (Ge)
- Arsenic (As)
- Antimony (Sb)
- Tellurium (Te)
- Polonium (Po)
What is a list of the properties of metalloids?
Asked by Wiki User
The metalloids generally:-
- Are brittle
- shiny
- have low enough band gaps to give them semiconducting properties
- form covalent compounds
Which shares electrons metals nonmetals or metalloids?
Asked by Wiki User
No. The nonmetal will take the electron from the metal, which makes this an ionic bond - not a "sharing" covalent bond.
What percent on the periodic table are metalloids?
Asked by Wiki User
Considering there are 6 metalloids on the periodic table and a total of 118 elements, metalloids make up 5.08% of the periodic table.
What ingredients contain boron?
Asked by Wiki User
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?
Asked by Wiki User
The metalloids are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium.
