Hope this help you mate...
Arsenic, for example, is a metalloidthat has the visual appearance of a metal, but is a poor conductor of electricity; metalloids...
An element that is not a metal but thathas some properties of metals. Arsenic,for example, is a metalloid that has thevisual appearance of a metal, but is apoor conductor of electricity; metalloidsare generally semiconductors. Theelements classified as metalloids areboron, silicon, germanium, arsenic,antimony, tellurium, and polonium.Metalloids can be viewed as a diagonalsection on the Period Table, separatingmetals from nonmetals.A nonmetallic element, such as carbon,that can form alloys with metals.
