Metalloids are elements with properties intermediate between those of metals and non-metals; Silicon is a metalloid because it has luster, but is brittle. Boron, arsenic, and antimony are metalloids with a … A metalloid, antimony resembles a metal in its appearance and in many of its physical properties, but does not chemically react as a metal. It is also attacked by oxidizing acids and halogens ( CRC, 1989 ). Arsenic, for example, is a metalloid that has the visual appearance of a metal, but is a poor conductor of electricity; metalloids are generally semiconductors. The elements classified as metalloids are boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. A metalloid is a chemical element that exhibits some properties of metalsand some of nonmetals.

Of the heavy metals and metalloid salts, the NaAsLL solution resulted in the highest EC and CuS[O.sub.4] solution resulted in the lowest EC. Transport characteristics of heavy metals, metalloids and pesticides through major agricultural soils of Bangladesh as determined by TDR Many translated example sentences containing "metalloid" – French-English dictionary and search engine for French translations. More broadly, metalloids have been referred to as:"elements that are somewhat of a cross between metals and nonmetals"; or"weird in-between elements". "In chemistry a metalloid is an element with properties intermediate between those of metals and nonmetals." "Between the metals and nonmetals in Metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal.

Nov 19, 2013 - Sb Antimony- is a Metalloid it can sometimes act like a metal or a nonmetal. Groups 1A-7A are usually classified as a representative element 

The known metalloids (and their atomic symbols) are: Boron (B) Silicon (Si) Germanium (Ge) Metalloid clusters of the general formula M n R m (n > m, M = metals like Al, Au, etc., R: organic substituents like Si(SiMe 3) 3 or ligands like PPh 3), which are actually often called “metal clusters” or “metal nanoclusters” or “monolayer protected metal clusters”, 43 are thereby ideal model compounds to understand the chemistry Is Astatine a non metal or a metalloid? Unknown. According to the Wikipedia article on astatine, the longest-lived isotope has a half-life of 8.1 hours.

I'm having a difficult time figuring out if Polonium and Astatine are regarded as a metal, a metalloid or a nonmetal. At Polonium is listed as a …

However, the metalloids' properties such as their ionization energy, electronegativity, and chemical reactivity differ from both the nonmetal and metal elements in the periodic table. These elements can be categorized as being either metals, nonmetals, or metalloids. The location of the element on the Periodic Table yields some clues about whether an element is a metal, a nonmetal, or a metalloid.

Depending on the author, one or more from selenium, polonium, or astatine are sometimes added to the list.
