  1. 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. The term is normally applied to a group of between six and nine elements (boron, silicon, germanium, arsenic, antimony, tellurium, and possibly bismuth, polonium, astatine) found near the center of ...

  2. May 8, 2021 · Elements are further classified into metals, non-metals, and metalloids. Table 2.11.1: Characteristic properties of metallic and non-metallic elements: Metallic Elements. Nonmetallic elements. Distinguishing luster (shine) Non-lustrous, various colors. Malleable and ductile (flexible) as solids. Brittle, hard or soft. Conduct heat and electricity.

  3. The elements in periodic table are organized by atomic number, or the number of protons. Metals are located on the left side of the zig-zag line (except hydrogen, which is a non-metal). Non-metals are found in groups 14 to 18, and they are poor conductors of heat and electricity. Metalloids are found along the imaginary zig-zag line.

  6. Mar 18, 2013 · If astatine does turn out to be a metal then, like other post-transition metals, it could be expected to show appreciable non-metallic character. Trace level experiments on the chemistry of astatine show that it appears to act like a metal in some respects and like a non-metal in others. The Wikipedia article on metalloids has more information ...
