It is the most important source for the metalloid antimony.

With the development of metalloid semiconductors, however, these elements have become among the most intensely studied'.

Inscrutable and silent behind their metalloid helmets, the watchers waited.

Mikah said, resting metalloid elbows on the tabletop at the club.

Typical fuels are based on metal or metalloid powders.

He fondled the metalloid container almost with reverence.

In such materials the hydrogen is bonded with significant covalent character to the second metal or metalloid atoms.

Hawkes suggests judging metalloid status separately for each element, given metallic character is a combination of several properties.

All metalloid hydrides are highly flammable.

Everything from the left to the metalloid "stairstep" is a metal, and everything to the right is a nonmetal.

When antimony is talked about it normally means the blue-white metalloid form, since it is most common.

Metal or metalloid atoms from carbides can selectively be extracted at high temperatures (usually above 1200 C) under vacuum.

Shading to either side of the metalloid column denotes immediately apparent commonalities, as compiled after the end of each table.

Brittleness or semiconductivity or both have been cited or used as distinguishing indicators of metalloid status.

Polonium dichloride is a chemical compound of the radioactive metalloid polonium and chlorine.

The metalloid element was not known in its pure form until 1808, when Humphry Davy was able to extract it by the method of electrolysis.

Szpunar (2005) defined metallomics as "comprehensive analysis of the entirety of metal and metalloid species within a cell or tissue type".

Most commonly, dry chlorine treatment is used to selectively etch metal or metalloid atoms from the carbide precursor lattice.

Chemical probes showed a metalloid structure rich in titanium, silicon, and carbon, but failed to identify the precise composition or molecular structure.

It should be a light, metalloid substance of readily identifiable nature, and it should be ductile and workable.

Compounds containing metal or metalloid bonds to hydrogen are often referred to as hydrides, even though these hydrogen centres can have a protic character.

Thompson R 1999, 'Re: What is the metalloid line and where is it located on the Periodic Table?'

(You hear it, of course, even in vacuum, because the vibration travels through the metalloid fabric of your space- suits-but there was hardly any bump, just a whisper.)

Replies: Dear Sam, Several of the metalloid elements have this property, as do some of the metals nearby the dividing line between metals and nonmetals on the periodic table.

The concepts of metalloid and semiconductor should not be confused.

It acts as a metalloid when compressed to high densities.

The origin and usage of the term metalloid is convoluted.

There is no universally agreed or rigorous definition of a metalloid.

It is sometimes referred to as a metalloid.

Because of its position in the periodic table, polonium is sometimes classified as a metalloid.

A semimetal or a metalloid is a chemical element.

During the 1920s the two meanings of the word metalloid appeared to be undergoing a transition in popularity.

The term metalloid was first popularly used to refer to nonmetals.

Selenium is commonly described as a metalloid in the environmental chemistry literature.

Astatine is usually classified as either a nonmetal or a metalloid.

It is not certain whether polonium is a metal or a metalloid.

It is a brittle, somewhat soft metalloid that is a little shiny.

Tellurium is sometimes not regarded as a metalloid.

Use of the term metalloid subsequently underwent a period of great flux up to 1940.

Classifying any particular element as a metalloid has been described as 'arbitrary'.

The notion of aluminium as a metalloid is sometimes disputed given it has many metallic properties.

Antimony is considered to be a metalloid and thus cannot be a noble metal.

It is a metalloid (it has properties of a metal and a non-metal).

It is a brittle and easily pulverized metalloid.

Astatine may be a nonmetal or a metalloid.

A third option is to include astatine both as a nonmetal and as a metalloid.

As an alloy, this metalloid greatly increases lead's hardness and mechanical strength.

The common allotrope of antimony is a blue-white metalloid.
