# Properties of Metalloids

Representative metals and non metals have been reviewed along with the properties of each. Some elements however are difficult to classify as one or the other. One example, is carbon. The diamond form of carbon is a poor conductor, yet the graphite form conducts fairly well. Neither form looks metallic so carbon is classified as a non metal.

Silicon looks like a metal. However its conductivity properties are closer to those of carbon. Since some elements are neither distinctly metallic nor clearly non metallic a third class called the metalloids is recognized.

The properties of metalloids are intermediate between those of metals and those of non metals. Although most metals form ionic compounds, metalloids as a group may form ionic or covalent bonds. Under certain conditions pure metalloids conduct electricity, but do so poorly and are thus termed semiconductors. This property makes the metalloids important in micro circuitry.
